The KDE blog entry reads like a modern political platform denying climate change, or claiming renewable energy can replace traditional energy sources on the grid.
One head strictly stuck in the ground and ignoring the cases that make many of those statements flatly false. Like for example, the nvidia support. Nvidia support in Linux is in the 'good luck' catalog, especially on any optimus laptop, where one is lucky if the power management works, much less multiple screen docking/undocking, and a heap of other issues. Then please clarify which actual driver stack one is running (nouveau vs provide by nvidia binaries, vs nvidia open source) To claim its great with wayland ignores core failures that still exist.
Its the same with X11 forwarding, which like copy paste, has been steady degrading to the point where all the dbus/etc services being depended on makes double digit percentages of applications not work with 'ssh -X' and oh wow, waypipe. It seems all of windows/osx and KDE/Gnome are steadily shooting themselves in the foot.
I'm sorta happy I pulled my financial support not long ago, there are a couple 'toxic' people in the distro DE community who are pushing their own agendas, everyone else be damned. And weirdly enough it seems those people aren't doing it for some corporate/whatever reason, but just to wave a flag about their accomplishments. The entire reason most people claim wayland is 'better' is largely FUD, but that doesn't stop the true believers.
