On the other hand, I don't think I've seen any developer release a game update enabling (what I understand to be) the essentially one-click "Linux support" EAC flag.
There is 0 chance of this happening. Anything in kernel won't be working at all, and I'm 100% sure that Activision won't make any effort to make it work on Linux.
None of the Kernel anti cheat work without being compatible with Linux which currently none of them are. EAC is supposed to be in the future but I doubt it will work.
Except that dev has to opt-in which I'm pretty sure none of the major studios will do, supporting another platform for a very vocal population with a few users.
Activision make a killing from selling DLC & Season Passes from their games like Call of Duty. Not sure why they'd give up free money from a single toggle switch with no extra work.
Unless out of spite, like when Snapchat banned third-party clients for Windows Phone (like 6snap) and accounts using it (I'm still raging that my 'benbristow' username got banned and now I'm using 'benbristow1' because of that).
Fun fact: The guy that made 6snap (and other 6 prefixed apps like 6tin (Tinder)) (Rudy Huyn) was hired by Microsoft and is now one of the leads behind the updated Windows 11 Store app
