The bottom line is that if I give something it should remain free. Of course
it's full of gray zones, particularly when people start adding value (as in
the case of, say, the commercial Linux distributions), since they could say
that they're selling the added value and not the object itself. I guess
restrictive licenses are easier to implement in that respect. When one
forbids everything, there are no gray zones. This why I almost no longer use
free models: I make my own or buy commercial ones. If I give away models,
I'd like the conditions to be clearly laid out so that users don't have
worry. Perhaps I should consider Public Domain after all.

I fear that enforcement is another annoying issue where people who have only
a moral stake are at a disadvantage...
