I'm sure SA could make a lot more money if he was more attentive to his customers. But obviously, money isn't his #1 concern, or he wouldn't have left DAZ in the first place. He's not a manager at K-Mart, he's an artist. And Poser is just a sideline to his real work.

He did announce at DAZ (and it was forwarded here to Rosity) that he was removing his products from the DAZ store, and that some of them might never be available again. So he did try to warn his customers to beforehand.
