I suppose I can see Blizz doing the whole money thing there, since they are a cash cow and think they can continue to do that. There should be no issue with having to pay for your nUI services since, afterall, you are helping tons of people for free regardless. Plus business is business, and businesses make money off businesses. This is jsut normal business. So for Blizz to butt into your business is jsut bad business. If someone doesn't want to pay for your product, then they can go find another product to use. nUI is not the only UI out there for WoW, there are quite a few, some more popular than nUI. So for Blizz to take issue over this is silly.
My support to you Scott.
