Re: What does vaccination have to do with software licencing?
Yeah, YOU can assert whatever weird terms you like in a licence (some of mine require the user to be nice to kittens, but nobody has ever said anything, likely because nobody reads that stuff), because one can take it or leave it (or get it legally smacked down for reaching into contexts that are irrelevant to that which is being licenced).
A bona fide "open source" licence should not. It should concern itself with exactly that which is necessary for the use of the software and/or source and no more.
Don't get me wrong, it's a good idea to fight back against the stupidity of the anti vaccine people, but it's not something that belongs in a software licence. I mean, let's start with an obvious question - how the hell do you plan on enforcing that?
