Actually don't blame DAZ, it's e-frontier that started the war in the first place.  DAZ tried to get the SDK from e-frontier for Poser 7 compatibility with Carrara 5 and they refused.  

In the old days, pre Poser 5 DAZ and Curious Labs were friends.  After Poser 5 rediculous EULA and attempts at product activation, Content Paradise was launched and they tried to steer Poser users away from Daz figures.  Apparently they resented the fact that Daz was developing Daz Studio.  Although other will disagree with me, I really don't think any of the native Poser people are as well made or versatile as the Daz Mil. Figures.  

If you import your runtime Libraries into your content tab you can drop and drag your Poser figures right in Carrara--that seems to work better than importing them by PZ3.   Why not just compose your scene right from the beginning in Carrara?  You can pose, morph, animate--it saves you an extra step!
