I couldn't edit, but I'd like to add that one of my main points is that Daz, in defending its trademarks against infringement by creators serving the same market, is not being a jerk or a money grubber, as so many seem to suggest, but it's just doing its legal duty to avoid losing those trademarks. Again, even though copyright can't be lost this way, there may well be some precedents in trademark law that mean a lax defense of copyright could affect trademarks of the same work. So Daz has to be extremely cautious in the way it permits use of its IP.
