The way I see it, no vendor is irreplaceable. If Stonemason no longer wants the money of Poser users, his loss. Someone else will pick up the slack. What we Poser users should be doing, is supporting those vendors who DO create for Poser, nurture them, and eventually we will foster a new Stonemason. We should support Poser vendors instead of complaining that Poser is not Daz Studio.
