Good old David - he loves systemd. No wonder he does not like X11.
Oldschool KDE devs were better. Today's generation of David or Nate, are just killing KDE off. But no worries, on their blog they'll continue how everything is great. It is so great that they need a donation-widget to keep on pestering people to donate. So now you can pay for them ruining the legacy here.
I don't really like Systemd neither - but Wayland and Systemd are pretty much opposites of each other. Systemd does (too) many things, many of them badly. Wayland does well what it does, but it (still!) does too little. Wayland is adding features and is pretty close to doing "everything necessary". Systemd keeps accreting worse replacements for existing services.
I dont know when where these "good old days" but in 2000s KDE was superunstable. It seemed to have all the cool UI tweaks but 30% of them barely worked.
Modern KDE is nothing like that, and i cannot see how this is a bad thing.
Funny, my impression of KDE in the 3 and 4 eras was “Wow, this is shiny and sleek— oh, and it crashed. Nevermind.” Nowadays there is nothing I would recommend more to the average user who just wants something normal that works. It just works. What you’re saying just sounds like a pointlessly personal and ideological attack. Against a piece of software. Why?
