He’s a Arch + WM user who loves to tinker. If that is you, then you’ll agree with his take. If you just want to get stuff done without tweaking your OS and without supporting Microsoft or Apple or Google and whatever BS they’re doing these days, then Gnome and Wayland are a godsend.
Even with GNOME I end up going down a tinkering rabbit hole because there’s so many papercuts that need fixing, many of which unfortunately can’t be fixed without making source changes and potentially even maintaining forks. Even after spending hours on my setup it still feels half-baked, which is irritating to say the least. Other DEs aren’t much better and sometimes even worse.
KDE is way better and really feels like a finished product IMO. Things you don't like you can just change unlike gnome which has almost no customization.
