I normally only check the readme for instructions as restrictions from bought products are normally in the renderosity EULA - which  says:-
"The Buyer may copyright any newly created rendered images using the purchased, original Product files, provided the original Product files remain protected from being extracted from the derivative work.  The Buyer may use the Product in rendered images for any personal or commercial projects, as long as the Artistís work is protected from extraction and the Buyer has not violated any other terms of the License."

So now a contradiction has slipped in.
Why oh why would a vendor feel he should do this. I mean I know it's their product and they have the right to do with it what they like, but there is such a thing as fairness, and it's fair to follow what is normal practice in this MP so buyers don't make mistakes, wreck their runtimes and jeopardize their profits from future projects.
I think the rendero EULA is perfectly fair.  Why go changing it?
