I once read a comment here or reddit explaining that the X11 developers moved to Wayland because the X11 code has turned into an unmaintainable mess that can't be worked with anymore. So the reasons are not drama, but just plain old tech debt.
Openbsd has brought in x11 into their own codebase: https://xenocara.org/
This is why openbsd is great.
I don't care about the drama that happens in Linux land at all.
The drama was mostly over whether or not Wayland should have been the replacement. AFAIU, everyone agreed X11 development was effectively unsustainable or at least at a dead end.
This pre-packaged talking point is often repeated without evidence. The vast majority of X.org developers, including all of the original ones, simply moved to other venues at one point or another. Only a few, like Daniel Stone, have made contributions to both. And it shows in how many lessons had to be re-learned.
