But he only cares about whether your application code generating responses on the server and the javascript running in your browser is Free under his definition. That in and of itself is not unreasonable — except that unlike every single other user on the planet, RMS doesn't give two shits about your data in a SaaS environment. The AGPL completely ignores what users actually care about the freedom of (data export), and focuses on stuff that's completely irrelevant (backend data munging). It may be simply because he has never used a rich web app, out of abject fear. He normally surfs the web via emacs+gnus+smtp+aliases+wget — he is not one of us, you can't argue with him on normal terms.
