I agree with you fully, sadly. I still buy a portion of my games on gog, especially during their seasonal sales, but more “just in case Steam dies” and to give financial support to gog so that they can stick around and keep doing what they are doing. Hopefully they (or a third party like Lutris or Heroic) will eventually get playing gog games on par with Steam.

It isn’t as seamless as Steam, but using Lutris or Heroic are the way to go if the games doesn’t have a native Linux version available on gog
