Erm... RTD does none of those things. There's a default site theme that is specific to RTD - they don't try to impersonate anyone. They don't "lift" anything unless the project owner has opened an account and requested that their documentation be hosted on RTD.
I'm at a complete loss how you've even come to the impression that RTD does the things you claim it does - because it does nothing of the sort.
