I think Arjan has definitely made some dick moves over the years. And Black Widow from Mr. Nice is the real white widow. Don't forget that Ingemar from Flying Dutchman also claims his White Widow is the origional. Arjan has one hell of a marketing team, and they are doing what boooky says they are. If you did grow one of "their version" it would still be pretty bomb chronic, just different in that it had different parents of similar breeding. I agree, its a total dick thing to do, and it does sucker in enough extra business to completely commercialize the Cannabis Cup and make it so you need millions to compete anymore.
That being said, any of thier hazes are indeed mostly Arjans. Once again, he has based his work on Neville's, but I think in the cases of his Ultra Haze #1, Haze #1 (which is much taller than the Ultra Haze #1), and also the Hawaiian Snow, He has used alot of genetics he gathered in south-east Asia and off certain Islands in the Pacific. Interesting Landrace genetics, grown for THC even in their country of origin. He also recently went to Africa to gather Landrace seeds used by Marijuana and hash croppers across the continent, so within the next couple years we will see if he will live up to the image he has created. I think alot of his stuff is good, but the jury is still out on his management and marketing styles. Let's see if he actually does something with the stuff he recently went looking for, even if he combines it with some of his older strains, it will be "his" and not Shanti-Baba's. He has a chance here, let's see what he does with it. If you do grow his stuff, it will not dissapoint you, I dont think. Everything I've ever had from them was pretty darn good.
