I'm sorry to hear the news, but this is exactly what happened to me.
DAZ said they wanted to sell all my products, we signed an agreement, and then they cancelled the agreement because of "negative comments" that they claimed I made. They didn't say what comments I made, where they saw the comments, or what made them so upset that they cancelled the agreement.
But most of all, they never offered to talk to me about these "comments" and resolve any issues like adults so we could both continue to make money. If we assume that DAZ keeps 50% of the product sale, then if I was making thousands of dollars in sales then DAZ is also making thousands of dollars in sales. Yet they're willing to cut off that income and terminate a signed agreement rather than talk things over.
And this may sound like a conspiracy theory, but I also wonder if there's some jealously from the top-selling PA's. After I made my agreement with DAZ, I quickly had 400 products listed on their site, making me the second-largest PA after RDNA. I don't think a lot of top PA's didn't like the fact that I suddenly jumped from 0 products to 400, especially when a lot of my products were older or were meant for use in Poser, Studio Max, or Vue. But the PA's shouldn't blame me since DAZ should have chosen not to upload those products.
So I think there's a similar situation here. Suddenly, Hivewire has a lot of products and they're taking attention away from the usual top PA's. And there's probably some truth to the idea that Hivewire's animals are better than the DAZ animals, which is probably why DAZ wanted to sell the products in the first place. But again, this creates jealously from the DAZ PA's who worked on those animals.
And like I said before, it seems like DAZ would rather terminate an agreement than discuss the issues.
