I agree that StackOverflow is at fault here, but enabling JS is not a binary choice — "allow all JS on this site" vs "block all JS on this site" are not your only options.

Tools like uMatrix allow me to control JS coming from different domains on different domains independently. For example, on SO I have enabled JS from Stack Exchange and related domains, but not from Google or other snoopers.
