Nothing from the conversation (or other things Stallman has said) supports the claim that Stallman believes charging money is evil. He believes that it's not good to restrict users' rights in certain ways, and perhaps that makes it hard for you to earn money with certain business plans that inherently depend on those restrictions, but there's no "right to earn money with all business plans", and that's nowhere near equivalent to a general belief that charging money is evil.

For example, as an opponent of large classes of patents, I don't believe that charging money to license patents in those classes is a business plan that should exist, which doesn't imply that I oppose charging money for things in general.
