But they can't pick a vendor who may host it better than the original authors. And the only reason for that is because the authors maybe would make less money that way.
"maybe would make less money" could be a catastrophic undermining of their business model, also ruining their ability to continue development, so I am very sympathetic to that reason.
Being stuck between "host it yourself" or "don't have the latest features" is pretty far from a rock and hard place.
