If Linux is to go mainstream I feel like KDE needs to be the default Desktop experience on distros. The Windows-like style is what the majority of people recognize and are familiar with and the KDE developers seems to care a lot about their userbase.
New users already has a lot to deal with and learn when it comes it Linux. They don’t need their desktop environment to work against them too.
I disagree with this, personally. There’s a lot more to initial usability/discoverability, than Windows-compatible visuals. If anything, when i’ve switched a couple of my family members off Windows, they asked me for something that doesn’t look like it, because they could never navigate through the desktop properly
There’s a proposal to make KDE the default in Fedora, I really hope this gets accepted.
If not, Fedora isn’t that great anyway. Universal Blue-based distros like Bazzite or Aurora are much better nowadays.
