I think they mean EA Anti-Cheat, not Easy Anti-Cheat. The former, which is used in 2042, does not run under linux (and probably never will).
BFV runs out-of-the-box on linux systems and has a "Gold" rating on ProtonDB. If EA really goes on with this, BFV will become unplayable, just like 2042.
You mean it the other way, right? Because these companies you defend use the free labor of voluntary developers from the community, which spend hours and hours developing features, fixing bugs and what not, directly or indirectly. That's how open source works.
When these companies change the project license to a closed source one, they're basically saying a big "f*** you" to the community. Forking the latest open source version of the repository is nothing more than an effort to keep things the way they were.
Linux is FOSS, you can do whatever you want with it as long as you redistribute it without modifying the license. Android does that; every GNU/Linux distribution does that. That's how it works.
What you're describing is "freeware", what this post is discussing is " open source software". There's a giant gap between the two.
