Ask HN: Where are the paid Linux desktop distributions?

Why isn't there any paid linux desktop distribution for personal use? I don't need enterprise stuff like RHEL, Ubuntu Pro or SLE and I don't really want the latest and greatest release of the usual distributions (often with breaking changes). I run something more stable i.e. KDE 5, which only has minor deficiencies for my setup. For obvious reasons I'm not yet switching to KDE 6.

Nonetheless, there are still a handful older bugs and occasional issues introduced through security updates. Which means finding, developing and applying patches myself.

Wouldn't it be cool, if there were some paid distribution, for a reasonable personal yearly subscription fee. Where you simply submit the bug reports & outstanding patches that affect you and that distribution would then slowly, but steadily (depending on popularity) backport fixes or even hire developers to develop fixes.

Does or did something like this exist?
