Poser is affordable and easy to use (in relative terms) and with time and practice, one can create some decent art with Poser.

I think the 3D artists who denounce it are annoyed by the fact that  the "unwashed masses" are starting to step on their toes and they're doing it by spending considerably less on software while  possessing generally less 3D computer graphics experience.

The fact they refuse to see is that although Poser is built on a foundation of pre-built objects, environments and textures, creating art in Poser is still far from "turn key" process.  As much as those 3D snobs would like to believe, it still requires artistic talent to produce decent results with what's available.

In that way, Poser shares something in common with photography.  Photographers haven't  always created what they photograph, so does that mean they're not real artists and what they produce is an inferior form of art?
