GPL is a more free license if one cares about having control over their computing. The BSD community cares a lot less about that in my (limited) experience and more about purely technical aspects. Which is fine, I just wouldn't expect them to hold if Linux is no longer an option somehow.

I've seen people in #freebsd attack GPL like it was thought up by satan.

That's the problem with BSD, the community holds a large amount of radical ideologies that led them to BSD. Like a deep hatred for systemd or the GPL.

Not the core developers though, just the community surrounding them.
