Oh I don’t say that it’s a good reason, it’s just why they do it. Shareholder value must go up. Trying something new risks that numbers go down, can’t do that.
Personally I don’t care for “triple A” games anymore. The last one I bought at full price shortly after release was 2019 for Jedi Knight, and that was a huge exception because the last before that one was 2010 for Mass Effect 2. All my other games in my way to big library are indies or games I bought on sale for less than 20 bucks and only because I’m interested in. I have blocked big publishers like EA or Ubisoft on Steam since a few years because of their attitude, enshittifiaction and mostly because their games are the same over and over again.
Edit: oh and because lot’s of their games don’t run (well) on linux anyway.
OpenXchange is also part of the IONOS group. I don’t understand why they don’t focus on one solution to make it as good as possible.
