Then your an absolute moron. This should be praised, they could have said fuck linux entirely but instead they said "hey native is costing us too much time, so instead we will just work on making sure our windows code is proton compatible"

That should be the goal, tired of worthless native purist assholes pushing developers away from Linux entirely by being little bitches about it. Game working is game working if proton is the easier path for the developer then cheer them on.
