I’ve found that you can play Rust on servers on linux. The only caveat is that the server has to either have EAC turned off or have their own AC, which on official servers is very rare. But its a lot more common on cracked servers (ArabArust for example). So if you really want to play Rust, you can. Just search cracked rust servers and look out for “Anti-Cheat” or something and you’ll get one.
