Without content the program would have died out long ago.
And without the program there would be no need for the content.

I'm reasonable sure, that 3D artists could live without Poser and content providers. But people, who are affected by Poser are sometimes not disposed to consider the alternatives. Shade could be good for those people. They might become inquisitive, if they have a real 3D modelling program at their hands.
Hmm, Shade might be the downfall of Poser.

You know what is right for you. I know what is right for me.
