The thing is that the politicians pushing for it genuinely want the 1984-esque mass surveillance. And it's not even some sort of mustache twiddling cartoonish evil, these are the sorts of people that genuinely believe if you're doing nothing wrong you have nothing to hide. That police should be able to get into any lock and read any message. That police are inherently good and won't ever misuse those powers once they have them. They're really just that naive.

The frustrating thing is that many of these people's voters, at least in the US, have always believed the Democrats are tracking them and just generally being evil while in power, and totally oblivious to the amount of control they offer up the government willingly. The idea that their beliefs might be persecuted is lost on them, despite not even that long ago saying they were.
