One could argue it was not given away for free, but with a silent expectation of reciprocity. Using open-source is a gentleman's agreement to be respectful towards the project, a good citizen, not to abuse and potentially contribute.

But you're right communities are now having to concoct a wild-growing collection of semi open-source licenses to protect themselves from abuse by a few big players.

Form a legal standpoint, you're correct.

From a moral/ethic one, its still shit.

You're legally allowed to do a whole lot of things. You can still be called an asshole for doing them.
