There is a free and open source bridge from DAZ to Blender. DAZ has one too, but more complete is the one from Thomas Larsson, available here:
https://diffeomorphic.blogspot.com/p/daz-importer-version-16.html

The complete Python source code is available. Figures converted are fully functional in Blender (it could be like that in Poser).

DAZ knows about the bridge. And almost any Blender user. Also from the commercial department. Means: Several thousand new users for DAZ figures. That's why DAZ wouldn't dream of banning the whole thing. Even if they could.

I'm not interested in a DAZ bridge to Poser, because I use studio and convert to Blender if I need it. That's why I haven't started implementing a DAZ/Poser bridge based on Diffeomorphics code yet.
