DAZ basically split with Poser, and I was moving into Blender anyway.
Plus I didn't like how DAZStudio changed to move away from Poser compatibility.

I have a HUGE investment in V3M3 family of figures, and felt no need or desire to move to V4M4.
Genisis went Crazy with the DSON stuff.

At this point I can model a figure from scratch in less time than it would take me to figure all the polotics and treaties involved with making everything work togther in Poser/Daz, and I can use that figure however I want with no fear of violating some one's TOS.

So between my growing more advanced, their growing apart, we just outgrew each other.
