Linus Torvalds currently uses Fedora with GNOME, which was fun to learn because that's also been my personal choice for a while now.

He seems to want as much stability as possible; while being as minimal as possible; with as little fuss to install and keep up to date as possible. Fedora meets those needs. Gnome is Fedora's main concentration.
Now, there's a separate build to download for KDE. It's likely because Gnome is default install for Red Hat Enterprise Workstation.
Most newer popular distros (Bazzite, CachyOS, Zorin, Asahi, etc.) default to KDE now, and it's very nice that Fedora's not only keeping up, but also providing the basis for some of them.
