I'm 99% sure this is a cease and desist. Mobius are masters in their craft and had no signs of slowing down.
The lifetime payments I got were money well spent because it hurts activision and their crappy milking of young minds.
I hope the devs behind the effort come back in some capacity. It's part of the chair game that providers will come and go. Let's try not to be toxic and be grateful they were around to offer awesome services.
I'm sure it wasn't an easy choice.
