nothing to do with the fact that the two figure models are werewolf's, nothing at all.  It has to be more than that like mesh used, UV's, texture, poses something in the Horde Product used in the Manitou product intentionally or unintentionally.

Renderosity doesn't publicly make statements on copyright cases acording to their web page, they pull the product in question and leave it to the parties involved in the claim to work out as they are the copyright holders and only they can defend their claims.

I had this product on my wishlist as I honestly thought it was an addon pack for SanctumArt's Horde product.  Something in this product made Micheal Rak (SanctumArt) make a claim and Micheal has been doing this for a long time and not just for Poser.

I don't think anybody should be dragging people's names through the mud about this.  It's between the two parties and the terms of the claim, not for to the public to decide.  Hopefully the Manitou product can be changed if needed to satisfy the claim of infringement and then both parties can move on.
