> I want to guarantee to my users that my software will always remain free [...] I always found this argument for GPL a little uncomfortable because of what it implies... let's be more precise: the existing code you publish whether using GPL or BSD will always remain free (it is irrevocably free); copyleft makes a distinction for freedom of derivatives i.e GPL forces people to make all future code free as well, this is about enforcing future investment not remaining free. To be clear I'm not dogmatic about either, I think both copyleft and permissive licenses have their place - it's simply subjective - some software feels more suited to GPL and others more suited to BSD.
