I do understand that some small projects with limited workforce will
need to rely on third parties and in that I see value in what Flathub
is right now, but:
* I don’t think there should be a single “Flathub” (as a repo hosting
platform), but that Flathub itself should indeed be the way to
discover the platforms[0].
* I don’t think GNOME apps should have been moved away from GNOME
infrastructure[1]. Yes, anyone can host their own repository, but if
even GNOME didn’t bother why would anyone else?
