Proprietary Javascript is bad, but in my opinion the situation is quite
similiar to the bios problem: no acceptable solution possible at the moment.
As I learned, LibreJS works inconvenient, noscript doesn't quite hit the
problem and the fsf campaign is a very good thing, but it aims to change the
behaviour of the web developers, so they want to change the whole web.
This will not be achieved tomorrow or in five days.
So what to do by now?
I think using noscript is a good way to embank the problem.
Not a solution, but an improvement of the situation.
