in X any application can turn into a keylogger, and you don't need a GUI for it, as long as the program can "speak X" it will be able to read the shared memory of all other programs the X server manages.
Not being able to participate in video conferencing and desktop sharing is an employment risk.
Im a picky person though. I already use i3, but also have NVidia gpu's. I don't mind spending some money on another real GPU (will it work with AMD).
I understand the frustration of the developers too. But screen sharing or my custom screenshot tool.. are things that will make me recompile if needed for days before I give up and abandon linux for the desktop.
I realize I'm spoiled, but I do wonder if this is the direction things are going who is going to be that hypothetical user that cares?
