The Dangers of Microsoft Pluton

This is the problem, when normal people stop buying PCs, only gamers and enterprise customers remain. So they will sell what their customers want.

I'd say that stage has already come, there's huge amounts of people where their main or only computing device is a phone or tablet. I've dealt with recruitment in a non-technical field and their phone is the online nexus point for them for any emails, documents, or website interactions. Even for gaming I'd argue PC is going into enthusiast territory and the GPU pricing situation hasn't helped that, consoles and phone gaming is strong and streaming has developed a niche.

And now the gamers want mostly online competitive games and their makers want the strongest DRM and kernel-level inspection all in the name of anti-cheat. We shouldn't be surprised if online games are one of the first spaces to require Pluton-enabled systems or no boot game.
