The Javascript issue never made sense to me. You are reading a non-free document to begin with, what difference does it make if it is running Javascript or not? If they wanna spy on you they can do that with HTML and CSS just as well. Even releasing the spying software under GPL wouldn't stop it from spying on you.
The party one should be angry about here is the browser, which provides little to no tools to show the user what is going on and provides no real means to stop it. This is quite a bit different from the early web days when every browser had a "Javascript off" and style sheet selector right in the main menu by default.

Not far enough. Ever since the whole world moved to "software as a service" and your computer has become little more than a thin terminal to some Google/Facebook/whatever-service FSF started to feel quite out of touch. Sure, they tell you "don't do that", but while that isn't wrong, it's not exactly helpful either. Many service simply have to run on a computer that you don't own and we need rules to govern that. None of the Free Software licenses help here.
FSF never bothered to create any kind of licenses or best practices that deal with how those services should work. They are stuck in dealing with software freedom problems of the 90s, not the problems we face today. Luckily we do have the GDPR now, but the FSF had nothing to do with that and never provided anything similar.
