"I think the real objection here is to people who use Carrara to render purchased content."

I clearly stated that I didn't have any problem with using the content, just that you shouldn't take credit for someone else's work.

"I just don't see the need to then go sneering at people who don't have modeling abilities, but still enjoy other aspects of creating 3d imagery."

Again, no objection to using content or sneering at those who do. Just give credit when it is due.

Several years ago this didn't happen here, people always stated where they came by objects that they didn't create themselves. The protocol was that if you didn't state that you got an object from somewhere else, then you created it yourself.

"A modeler should receive either recognition or cash, I seen no reason for both"

I'm amazed at this comment. So you buy a vehicle from 3D02, render it and then let everyone think you modeled it. I hope you don't use these tactics when applying for job somewhere, it would be considered fraud.
