As in they're under a license agreement that prohibits open-sourcing?

Presumably unless it's specifically prohibited then they could release their code with holes where the licensed content goes, which would bump the problem up the chain to the next layer of owners and allow people to focus on them? Or let people adapt the codebase to work around the other libraries (or whatever)??

Opera did a lot for the web.
