I can't say I'm surprised, though I am disappointed. He was using non-SRD content without a licensing agreement or anything like that. With Beyond out there, it was just a matter of time before he was shut down. Really though, it was a solid product and WOTC probably should have hired him and his team to do Beyond. Trying to make money on a product that uses someone else's IP will get you that cease and desist though.
To my knowledge, there was no team. It was a one-man operation as a side-gig/hobby for him. Which makes it that much more impressive.
