At the end of the 2020 season, it was reported that Oka was one of several riders who filed complaints to the
UCI about team manager Philippe Lannes trying to force them out of the team midway through their contracts and evict them out of the team house, amidst controversies over "missing payments, contracts not being honored, and threatening behavior" towards the riders' futures on the team.
