You mischaracterise KDE - they are running the same platform, but they are very much not trying to converge user interface at all, which seems to be your main complaint.
If anything, I think KDE's approach looks like the best I've seen.

Sorry, I don't know KDE Plasma Active too well; I thought that the point of KDE Plasma was to unify all environments. If not so, I apologize.
Anyway I am not complaining, I am just amused that so many people think that convergence is the future, when successful platforms do just the opposite.

unify on a technical level, sure. But the goal of Plasma since day one (and that is well over 4 years ago) has always been to be able to build completely optimized ui's for each formfactor, despite sharing most of the heavy lifting. It is very modular and the team claims that despite the completely different way of working, desktop, tablet and phone share 90+% code.
