Their blog post about this subject is really good https://www.ondsel.com/blog/goodbye/

They chose maybe one of the toughest imaginable combinations for a business model. Viable open source businesses are hard (since you don’t own your ip in closed form, hard to explain to investors what the actual value is). 3D businesses are hard.

So it’s hard x hard.

Clearly their _tech_ worked. I guess there is a lesson here - better mousetrap is almost never enough for a viable business.
