Yeah, so the problem with that is you're typically not building a security platform with a game on top, you're building a game. The scope of the issue is not the same for Fortnite or LoL than for... I don't know, Fatal Fury City of the Wolves, if we're getting topical.

Especially in a multiplatform game where the PC is not your primary target and your targeted consoles have a semblance of platform integrity it is not unreasonable to expect the platform to handle at least the basics. And hey, if Windows gives you that through a third party service that's resources you can put in... you know, the game part of the game.

That's not being lazy, that's the second law of thermodynamics. Resources are limited, from developer time to server time (which goes up if you can't offload literally anything to the client).

You're more likely to have me meet you in the middle if we agree that there probably should be a middle ground where the layer of security that is now being offloaded to a third party service having kernel-level access should instead be handled by the OS. I don't know if that's better or worse, but it certainly isn't as weird and scary as having a bunch of mid-sized vendors have crazy access to people's computers just so they can play games semi-functionally. But to bring this back to the original argument, that sounds like something you're at best going to get from Microsoft. Linux being what it is, that isn't an option and is not going to become one.
