Well, for me at least, his advocacy for Free Software is irrelevant to his assertion that his open source project should not require a ToS and login to contribute to. It might explain his motivations, but it doesn't invalidate his position, imo. Others may agree or disagree with him (or I) on these things.
I am not sure. This is a somewhat difficult to argue but if he called himself a free software supporter, I think he's more than just an open source advocate. He's a free software advocate so he rejects any proprietary software right away.
Popular OSS such as Firefox and Python still require you to register on their own system before you can submit a bug report. Is that behind a ToS? Yes. Thus, ToS or not is not the issue here. His entire point is his rejection of using any proprietary, for-profit service to run and manage his project -- because he's a FS advocate.
I am not from the Free Software camp, but in the old days, when sourceforge was still popular, I believe any free software hosted on sourceforge would be considered a violation of Free Software.
