I am a strong linux supporter and I too do not like what proton is doing to games. A few years ago there were many significant games coming out with native linux capacity (MineCraft, KSP, Factorio). Then proton dropped. Now, rather than support linux natively, even the most pro-linux developers are just expecting that their windows version will run under proton. And those who are running games under proton are essentially cut-off from customer support. I've had a few games where a patch suddenly stopped them working under proton. I have no recourse in such situations. That is not a good trend.
