It might be difficult to find a formal and logically coherent definition of "restrictive" vs. "permissive", but I was thinking in more pragmatic terms. Like with porn, "I know it when I see it". As I see it, required attribution somewhere in the docs is not very restrictive. On the other hand, 20 pages of legal mumbo jumbo concerning distribution are restrictive.
