While I realize you just want to vent, I can't help but add my two cents...
I DO think that Adobe rushed out the latest version of CC to meet an artificial deadline (Adobe MAX). I thought this "rush to release" problem went away with CS; CC was supposed to eliminate this issue. But the marketing dept. always trumps the programming dept. Also, the Mac M1 chip seemed to throw them off track too.
That said, a lot of the problems come from problems on the user end, such as outdated GPU cards or drivers. I, for one, have not had any major problems with Adobe software on my systems (Win 10, Win 11, Mac 12.x).
Another issue seems to be lack of knowledge of maintaining software. If I'm making money with my software (which I do), I would not blindly update to any new version. Users could have controled the CC app preferences to install or not install new versions, and to remove or not remove old versions. Keep and use stable versions until one feels the latest releases are ready for "prime time".
Finally, Adobe does not fit the definition of a monopoly. There are plenty of alternatives--some are open sourse (usually free). It is popular by user choice, and some clever marketing to colleges back with the original suites.
