The KDE to GNOME should have been "imagine not having standard min max window titlebar buttons by default" with each following DE dunking on GNOME for the same reason.
Seriously, what degenerate thought this was a good idea. Even gesture spamming Mac users still have their standard GUI in case they want to use the mouse like a normal person or idk someone not fluent in computers wants to use the machine without feeling like chopping their hand off.
Yeah the XFCE dunking of KDE doesn't even make sense these days - a fresh XFCE system has similar memory use to a fresh Plasma desktop with similar features.
(To be clear: the only one of those dunks I actually feel was deserved was the dunk on gnome.)
