EAC is functionally useless on Linux and can be defeated by anyone with the ability to sudo or to boot a modified operating system. Steam Linux does not supported sealed/signed boot with secure attestation, and supporting 1% market share options that do (if any) is unrealistic for developers, so it’s perfectly sensible for PvP multiplayer games to ban Linux users. Not out of malice or disrespect but out of simple technical incapability to detect unskilled cheaters using purchased toolkits.

Removing the single player mode from Linux, however, suggests that they’re doing this because any platform without multiplayer is worthless to them, which suggests there must be a ‘skin shop’ in this game that is viewed as the primary revenue generator. That decision is extremely disrespectful — but it’s the same disrespect they might show by not selling the single player game in countries that disallowed predatory loot boxes, for example. I wholeheartedly support naming and shaming that disrespect; here, they’ve mixed it with complaints about cheating to (largely successfully) disguise a cost-benefit analysis as out of their control due to Linux.
