> I find that most BSD users don't really care about such legalese and most people I know that run FreeBSD are running ZFS on root.
I don't think it's that they don't care, it's that the CDDL and BSD-ish licenses are generally believed to just not have the conflict that CDDL and GPL might. (IANAL, make your own conclusions about whether either of those are true)
Hmm yeah but that's the thing, who really cares about licenses as a user? I certainly don't. It's just some stuff that some lawyers fuss over. I don't read EULAs either nor would I even consider obeying them. The whole civil-legal world is just something I ignore.
I do have a feeling that Linux users in general care more about the GPL which is quite specific of course. Though I wonder if anyone chooses Linux for that reason.
But really personally I don't care whether companies give anything back, if anything I would love less corporate involvement in the OS I use. It was one of my main reasons for picking BSD. The others were a less fragmented ecosystem and less push to change things constantly.
