Comment If users blindly follow ISP instructions (Score 1) 177
This seems no different, since it's up to the browser (not just the ISP) to enable the trusted proxy stuff. If a browser enables it without your consent (just as if they deliberately add a bogus CA to the trusted cert list), the browser is being evil and needs to be fixed. If it is left to the user, who enables it without understanding, that's unfortunate, but no worse than what can currently happen.
