I suspect KDE because most PC gamers are Windows users and KDE is closer to that while Gnome is closer to macOS (both in design and being restrictive).
For what it’s worth, when I moved from macOS to Linux I found that KDE Plasma customisation made it less frustrating to get the appearance and multitouch gestures closer to what I was missing on a Mac.

There’s some small issues with the alt key behaviour in some applications (and workarounds for that), but other than that it works really well for my OS X configured brain.
I’ve used the Spoiler Protection 2.0 extension in the past, though it hasn’t been updated in a long time so there may be a better option.
It doesn’t block content but places a big red overlay over links, headlines, images (that are tagged) and videos. It’s not fool proof but definitely useful if you want to block “Trump” or “Musk” or whatever else.
