The Info List - Vendor Lock-in

--- Advertisement ---

In economics , VENDOR LOCK-IN, also known as PROPRIETARY LOCK-IN or CUSTOMER LOCK-IN, makes a customer dependent on a vendor for products and services , unable to use another vendor without substantial switching costs . Lock-in costs which create barriers to market entry may result in antitrust action against a monopoly .

Main article: Criticism of Microsoft § Vendor lock-in

The European Commission
European Commission
, in its March 24, 2004 decision on Microsoft's business practices, quotes, in paragraph 463, Microsoft general manager for C++
development Aaron Contorer as stating in a February 21, 1997 internal Microsoft memo drafted for Bill Gates
Bill Gates
: "The Windows API is so broad, so deep, and so functional that most ISVs would be crazy not to use it. And it is so deeply embedded in the source code of many Windows apps that there is a huge switching cost to using a different operating system instead. It is this switching cost that has given customers the patience to stick with Windows through all our mistakes, our buggy drivers, our high TCO, our lack of a sexy vision at times, and many other difficulties. Customers constantly evaluate other desktop platforms, it would be so much work to move over that they hope we just improve Windows rather than force them to move. In short, without this exclusive franchise called the Windows API, we would have been dead a long time ago. The Windows franchise is fueled by application development which is focused on our core APIs"

Microsoft's application software also exhibits lock-in through the use of proprietary file formats . Microsoft Outlook
Microsoft Outlook
uses a proprietary, publicly undocumented datastore format. Present versions of Microsoft Word have introduced a new format MS- OOXML . This may make it easier for competitors to write documents compatible with Microsoft Office in the future by reducing lock-in. Microsoft released full descriptions of the file formats for earlier versions of Word, Excel and PowerPoint in February 2008.

§ Accusations of anti-competitive behavior

Prior to March 2009, digital music files with digital rights management were available for purchase from the iTunes Store , encoded in a proprietary derivative of the AAC format that used Apple's FairPlay DRM system. These files are compatible only with Apple's iTunes media player software on Macs and Windows , their iPod portable digital music players, iPhone smartphones , iPad tablet computers , and the Motorola
ROKR E1 and SLVR mobile phones. As a result, that music was locked into this ecosystem and available for portable use only through the purchase of one of the above devices, or by burning to CD and optionally re-ripping to a DRM-free format such as MP3
or WAV .

In January, 2005, an iPod purchaser named Thomas Slattery filed a suit against Apple for the "unlawful bundling" of their iTunes Music Store and iPod device. He stated in his brief: "Apple has turned an open and interactive standard into an artifice that prevents consumers from using the portable hard drive digital music player of their choice." At the time Apple was stated to have an 80% market share of digital music sales and a 90% share of sales of new music players, which he claimed allowed Apple to horizontally leverage its dominant positions in both markets to lock consumers into its complementary offerings. In September 2005, U.S. District Judge James Ware approved Slattery v. Apple Computer Inc. to proceed with monopoly charges against Apple in violation of the Sherman Antitrust
Act .

On June 7, 2006, the Norwegian Consumer Council stated that Apple's iTunes Music Store violates Norwegian law. The contract conditions were vague and "clearly unbalanced to disfavor the customer". The retroactive changes to the DRM conditions and the incompatibility with other music players are the major points of concern. In an earlier letter to Apple, consumer ombudsman Bjørn Erik Thon complained that iTunes' DRM mechanism was a lock-in to Apple's music players, and argued that this was a conflict with consumer rights that he doubted would be defendable by Norwegian copyright law.

As of 29 May 2007 , tracks on the EMI
label became available in a DRM-free format called iTunes Plus . These files are unprotected and are encoded in the AAC format at 256 kilobits per second , twice the bitrate of standard tracks bought through the service. iTunes accounts can be set to display either standard or iTunes Plus formats for tracks where both formats exist. These files can be used with any player that supports the AAC file format and are not locked to Apple hardware. They can be converted to MP3
format if desired.

As of January 6, 2009, all four big music studios ( Warner Bros.
Warner Bros.
, Sony BMG
Sony BMG
, Universal , and EMI
) have signed up to remove the DRM from their tracks, at no extra cost. However, Apple charges consumers to have previously purchased DRM music restrictions removed.


Although Google
has stated its position in favor of interoperability, the company has taken steps away from open protocols replacing open standard Google
Talk by proprietary protocol Google
Hangouts. Also, Google's Data Liberation Front has been inactive on Twitter since 2013 and its official website www.dataliberation.org now redirects to a page on Google's FAQs, leading users to believe the project has been closed.


* Many printer manufacturers claim that if any ink cartridges, beyond those sold by themselves, are used in the printer, the warranty of the printer becomes void. Lexmark goes further , making ink cartridges that contain an authentication system, the purpose of which is to make it illegal in the United States (under the DMCA ) for a competitor to make an ink cartridge compatible with Lexmark printers. * Test strips for glucose meters are typically made for a specific make or model. Strips designed for Accu-chek devices, for example, are incompatible with meters from other manufacturers. This lack of standardization can lead to problems especially in developing countries , where glucose meters and their associated strips are a scarce commodity. * The K-Cup single-serving coffee pod system was covered by a patent owned by Keurig
, which is a subsidiary of Green Mountain Coffee Roasters , and no other manufacturer could create K-Cup packs compatible with Keurig
coffee makers without a license from Keurig. While the company does have patents on improvements to the system, the original K-Cup patents expired in September 2012. Other single-serving coffee brands, such as Nespresso , also have proprietary systems. * Lens mounts of competing camera manufacturers are almost always incompatible. Therefore, a photographer with a set of lens mounts of a certain manufacturer will prefer not to buy a camera from another manufacturer. * Nvidia
, as of 2017 still only supports a proprietary Nvidia G-Sync despite the availability of the open Video Electronics Standards Association (VESA) standard Adaptive Sync technology ( FreeSync ). * Many hotels offer rooms at a discounted rate, but with vendor lock-in in the form of cancellation fees. They advertise the discounted rate to attract footfall, while persuading customers about to book to pay the full rate.

Monopolistic Whether a single vendor controls the market for the method or technology being locked in to. Distinguishes between being locked to the mere technology, or specifically the vendor of it.

This class of lock-in is potentially technologically hard to overcome if the monopoly is held up by barriers to market that are nontrivial to circumvent, such as patents, secrecy, cryptography or other technical hindrances. The heat equation describes one particular dynamic of smoothening a spatially distributed parameter. Depicted: A simulation of temperature on a two-dimensional surface. Collective Whether individuals are locked in collectively, in part through each other. Economically, there is a cost to resist the locally dominant choice, as if by friction between individuals. In a mathematical model of differential equations, disregarding discreteness of individuals, this is a distributed parameter system in market share, applicable for modeling by partial differential equations , for example the heat equation .

This class of lock-in is potentially inescapable to rational individuals not otherwise motivated, by creating a prisoner\'s dilemma — if the cost to resist is greater than the cost of joining, then the locally optimal choice is to join – a barrier that takes cooperation to overcome. The distributive property (cost to resist the locally dominant choice) alone is not a network effect , for lack of any positive feedback , however the addition of bistability per individual, such as by a switching cost, qualifies as a network effect, by distributing this instability to the collective as a whole.


As defined by The Independent
The Independent
, this is a non-monopoly (mere technology), collective (on a society level) kind of lock-in:

Technological lock-in is the idea that the more a society adopts a certain technology, the more unlikely users are to switch.


* The continued prevalence of the QWERTY
keyboard layout is said to be caused by technological lock-in. * Carbon lock-in is the theory that society has become reliant on carbon intensive technologies, thereby hindering renewable energy commercialization . * Converting one lossy file format into another is a tradeoff between further loss in quality and increased size. Therefore, if valuable content is encoded in the format, this creates a need for continued compatibility with it.


Technology lock-in, as defined, is strictly of the collective kind. However, the personal variant is also a possible permutation of the variations shown in the table, but with no monopoly and no collectivity, would be expected to be the weakest lock-in. Equivalent personal examples:

* A person who has become proficient on QWERTY
keyboards will have an incentive to continue using QWERTY
keyboards. * A car owner has an incentive to make use of her car, because using it is cheap compared to the total cost of car ownership; the car is said to be a sunk cost . * A person who has ripped his CD collection to MP3
will have an incentive to prefer audio equipment that supports this format; and vice versa, for personal investment reasons, has an incentive to continue ripping to this format. * A person who has most of his multimedia equipment interconnected with HDMI
will tend to seek HDMI
compatibility to all his other multimedia-capable equipments.


There exist lock-in situations that are both monopolistic and collective. Having the worst of two worlds, these can be very hard to escape — in many examples, the cost to resist incurs some level of isolation from the (dominating technology in) society, which can be socially costly, yet direct competition with the dominant vendor is hindered by compatibility.

As one blogger expressed:

If I stopped using Skype, I'd lose contact with many people, because it's impossible to make them all change to software.

is both patented and entrenched, as noted by Richard Stallman
Richard Stallman
in 2001 (in justifying a liberal license for Ogg Vorbis ):

there is (…) the danger that people will settle on MP3
format even though it is patented, and we won't be *allowed* to write free encoders for the most popular format. (…) Ordinarily, if someone decides not to use a copylefted program because the license doesn't please him, that's his loss not ours. But if he rejects the Ogg/Vorbis code because of the license, and uses MP3
instead, then the problem rebounds on us—because his continued use of MP3
may help MP3
to become and stay entrenched.

More examples:

* Proprietary file formats that have become widespread on the web : examples include GIF
(patent expired), Adobe Flash
Adobe Flash
and H.264 . * Communication services that require membership with the same vendor as the communication partner: Unlike telephone service providers , which enable communication with competing providers' users, services like Skype
and Facebook
are effectively single-vendor communication protocols. Facebook
is said to have achieved technological lock-in, in terms of its self-reinforcing presence on a society level. However, if the lock-in is to Facebook
specifically, not social media in general, then it is fair to promote this title to collective vendor lock-in.
