Well, since this survey does in fact include "nonfree" javascript it would imply the authors don't subscribe to that mindset but mentioned it out of respect to those who do.

I'm not sure how much this inhibits Emacs. It's architected in a certain way and there's decades of elisp code one wouldn't want to throw away. IMO this is the biggest limiting factor. Most big fundamental improvements would mean giving a lot of stuff up.

Not a huge fan of "free" software absolutists but just haven't seen this come into play too much with Emacs.
