I agree with that first paragraph. My main disagreement is about your use of 'No'. I don't see how what you say contradicts what I said. Care to explain?

I won't comment on paragraphs 2 and 3, because they, to me, look more like opinions than factual discussion.

The last paragraph, similarly, IMO is not built on facts. "The corporate world uses the GPL" certainly isn't uniformly true. To mention one example: from what I can see, a C compiler is part of the "really important stuff" and clang is more popular than gcc for new developments.
