You either put some trust into the systems made by other people, or you don't touch computers at all.
different goals, different people involved, different scope of access, different amount of review, different amount of use = different levels of trust
it appears like you are saying "if you trust the font to be okay, you should trust anti-cheat". but we've just cleared up that they have wildly different levels of trust, due to their wildly different access, size, purpose, etc.
it's either completely and honestly someone not technical missing the point entirely, or more likely trolling.
