The problem with that logic is that Stallman missed a huge point.
If, from his example you're using Google Docs, even if the JavaScript is "freed" using his new standard with stylized comments and the @source directive - you are still accessing non-free server software (the Google web servers) that responds to the AJAX requests.
Not only that, but your browser is also making a call to the Google Ad server, which also has non-free software. You might also argue that its being served by a modified version of MySQL thats non-free, and perhaps even the firewall and the proxy that its passing through is a custom version written by Google Engineers (likely.)
