The anti-cheat argument is an interesting one. It's not merely an obstacle to Linux adoption (it's also not special in that regard; just another first-party-support problem). It's a cultural problem that we cannot fix with technology.
Intrusive anti-cheat exists for a very simple reason. Many game developers will neither grant users the ability to moderate their own spaces (as they once could) nor dedicate the appropriate resources to do so themselves. If they did, server-side heuristics would largely suffice.
Furthermore: evangelism is good. Without it, Linux would be nowhere near what it is today. Even if the platform somehow magic'd itself into getting both end users and manufacturers to give a damn without the other one already having done so, and it could in this manner achieve feature and accessibility parity with Windows, people still wouldn't jump ship. Without some kind of major technical argument in favor of Linux (which is not likely to happen as all 3 major x86 OSes are pretty much always cutting-edge), the ideological angle is the best one we have.
