Someone on reddit wondered if this is the embrace phase of embrace, extend, extinguish.

This is what most people arguing in favor of this don't get. This changes the entire ecosystem via some kind of peer-pressure once more and more game developers implement EACv2 (from the side of both developers as well as players). And other AC vendors like BattlEye will likely also follow suit. Imagine letting Tim into your kernel... I'm not even letting Gabe into my kernel.

Also RIP custom kernel modifications/tweaks for the sake of performance or new features if you want to play any future game which will implement EACv2. Also RIP applying in-development or bugfix patches, especially AMDGPU ones. And RIP OOT modules for niche hardware that's not packaged by the distro.

Personally, I don't even play any competitive multiplayer games so I generally have no interaction with anticheat one way or another. For that reason, I don't see myself doing the steps required to get EAC v2 working.

But, given that there are loads of people who:

1. Want to play and enjoy these competitive multiplayer games
2. Don't want cheaters to ruin the game for them
3. Acknowledge that cheaters will ruin the game if nothing is done to prevent that

Then, some trade-offs are inevitable. Anti-cheat is required for that, there's no getting around it. That is the "good reason" for which the attestation is needed.

Maybe for you that's not a good reason - that's fine, it's the same for me, I just don't play those kinds of games and so the games I play don't need anticheat. There's really no reason to get angry with a solution that DOESN'T AFFECT YOU if you're not interested in it, but actually serves a purpose for others.
