Linux I was on about the forced changes to wayland / pipewire, etc. Gnome is the biggest example of that but KDE is now doing it to.
Wayland is not aiming to be compatible with X11 and it breaks a ton of stuff. For example its messing with the tk scaling in our python app with no obvious way to signal it not to do that as its doing it wrong making the text to big.
But theres also a ton of things like screen recorders that cant handle wayland. To fix the ones that do support wayland you need stuff like pipewire. Pipewire also isn't perfectly compatible and breaks audio codecs in xfreerdp and isn't compatible with my pulseaudio config file. I haven't found an obvious way to port it yet.
For gnome users its especially bad because they simply refuse sensible requests like implementing serverside decorations for their wayland version. By dropping X11 every app is now forced to program window borders to have them on gnome which will force everything to switch to client side decorations so none of the border consistency will work anymore if apps bother to begin with.
Then there are the endless library incompatibilities. The fact ubuntu is replacing core utils with an incomplete rust version, etc.
The developers behind a lot of it love promoting their political ideologies and love to shut genuine concern down. They want to force their ideas down the entire ecosystem and it shows. And because people who aren't in favor are villified or leave out of frustration they rule the ecosystem now.
