Well the thing with those "enabled EAC on Linux to see where it gets us" is it's non-binding and non-commital. And it's made explicitely that way so that support cannot be demanded from Linux users unlike Windows users who are explicitely mentioned in the systems supported by the game.

We legally don't have any ground to be supported the same as Windows users.

That's the problem with non official support. You're basically in an unending beta-testing phase. Theres' no easy solution here I'm afraid.
