Is Ubuntu demanding they pay for that work in cash or code? Obviously not, since Ubuntu generally offers it for free. You think they do that out of the goodness of their hearts? I don't. I think they benefit from people using their software even for free, otherwise they wouldn't do it. Whatever that benefit is, they'll get less of it if people reject their software because Bluetooth sucks (for example). Suppose that gives them incentive to do something about it. Then what's the problem? Sounds like an efficient market interaction to me.

Ubuntu pays developers. The more they pay one kind of developer the less they're able to pay other kinds of developers. So yeah. That really is a trade-off for Ubuntu.
