I think most people want to own their renders.  If they have a whole lot of freestuff mixed in their runtimes with their good stuff, and half the readmes missing, the only way to be sure they own the renders, if say one day they want to sell one, is to start their runtime all over again.  for me that would be a disaster.  Some people don't have external runtimes.   They have everything in one big runtime.
I am sure you are right about their chances of being sued being miniscual, but none of us want to do anything illegal.
