I've been with linux for 20 years now and at one point GOG was the place to go, because DRM was one of the biggest problems with wine.

I downloaded all my games stopped using it after they came up with their own electronic store, which I thought was a horrible shit and very clunky on wine.

Steam and proton were rising at the same time and more and more games were working without the usual fuss of installing .dll files, obscure media codecs, .net and etc, so it was bye bye GOG.
