You don't really need copyleft protected software. The BSD community is very much alive. The important point is actually use the type of software you care about. If you care about copyleft, use as much copyleft software as you can, if you care about BSD, use BSD systems. In particular, if an open source version is available but you take the closed source version because it is somehow nicer, you are sending a message that you don't actually care. And the only way we can keep open source alive is if we care. Just using it helps. Reporting bugs helps.
