It’s never about the DE’s themselves, it’s about the devs.
KDE’s devs are just focused on making a cool desktop environment with many features. It’s a little buggy and has some weird design decisions, but whatever, no biggie.
GNOME devs deliberately sabbotage existing linux standards in attemps to take control over desktop linux. Examples: client-side decorations, client-side shadows, systray fiasco.
This is not a question of personal preference. It’s a question of keeping desktop linux free, fair, and accessible for everyone.
Did you even read my comment? This has nothing to do with personal preference. It’s a matter of defending a shared commons from a hostile force. Sure, an individual gnome user can coexist with an individual kde user, like seriously who cares its just a DE. But as a community, users of other DEs, WMs and compositors can only “coexist” with the gnome project in the same way that a population of humans can “coexist” with the COVID-19 virus
