If it was an issue on the user’s end then it’s possible 3rd parties could fix it (as Wine/Proton has for every game not designed for GNU+Linux). BattleState Games have decided they don’t want to host servers without BattlEye for us to play on and that we’re not entitled to host our own servers.
I did consider installing Windows on a machine just for Tarkov but install and using modern Windows looks like hell. I’d rather install Windows XP than Windows .
