I'm not very impressed by many of the licenses produced in recent years. Often they're seeking to produce a closed ingroup of beneficiaries. It's this sort of clubbishness which was one of the main hallmarks of proprietary licenses. If you're in the corpus or the chosen few in the magic pentangle then maybe you get access/use rights, but otherwise you're just plain out of luck.
