I see! My metaphor was mainly meant to illustrate that whether anticheat is directly related to the current security issue is orthogonal to why I thought it was relevant to bring up. I could have picked a better one that didn't imply that their misplaced concern about Linux cheaters actually consumes resources.
Maybe a better metaphor would be a municipality refusing to do something about a small issue (maybe poor transit to a specific neighborhood) and also actively refusing to let that neighborhood solve the problem themselves (proton devs) with the excuse that allowing that neighborhood to have transit would cost too much (even if the neighborhood were to do it themselves) and cause more crime (painting Linux users as hackers) all the while some completely unrelated group is actually causing the crime elsewhere.
Wow, sounds like they're only sorry that they didn't fire him the right way. And all over sharing an article without adding any comment.
