Yep. I just read last Stallman's article and I'm lost. Unless I completely missed something, this idea is totally stupid. So, let me try summarize his point : the web pages a user browses load/use JavaScript code. Free Software philosophy applied to the Web should provide the user with a way first to know the license of the JavaScript code a page is using/loading, second to replace that JavaScript code with a piece of his/her own. Fine. Great.

Now, the author of the web page modifies his/her page. Or even revamps it entirely. The old JavaScript code becomes irrelevant here but the new one keeps the URL of the old one. The user-modified version of the JavaScript code does not work because it's made for a page that is completely different. The Web page is then not browsable in a normal way and the whole user experience is trashed.

Can someone explain me what's good here in RMS's idea because I fail to see that part...
