There are other reasons too:

* Time pressure - OSS is rarely under deadline pressure so the temptation to half ass it is mitigated.

* Survivorship bias - there's actually a lot of OSS shit out there too but it is much easier to ignore coz nobody is gonna force you to use it.

Similar to your survivorship bias, just because something is done for free doesn't mean it's an insignificant "nothing" project, and just because you sell something doesn't mean much effort was put into it.

You could be comparing the work of hundreds of dedicated engineers for over a decade to something someone threw together in an afternoon, that was never intended for mainstream use... sure they're charging $20k for it, but that doesn't make it "good".
