It’s probably a tiny fraction of the C#/dotnet ecosystem. But hobbyist meme creators mostly care about games, I guess.
No, as other’s have pointed out it’s not. There are plenty of other areas to use it, even in other game engines. OP is just trying to make it seem funny by making the exaggerated narrative that it’s the only use case for C#. If Boo was still around in Unity this joke would been accurate with that, don’t think that was used anywhere else
I mean Windows is also undergoing enshitification it could still be true?
While true, businesses have it even harder to migrate to Linux (what else is there when talking enshittification?) than private users. Windows and dotnet won’t go anywhere anytime soon.
