The privacy points in general are valid, but what irritates me is using this rationale against kernel mode anti cheats specifically.

You do not need kernel access to make spyware that takes screenshots. You do not need a privileged service to read the user’s browser history.

You can do all of this, completely unprivileged on Windows. People always seem to conflate kernel access with privacy which is completely false. It would in fact be much harder to do any of these things from kernel mode.
