And I'm not saying that someone worrying about affording food and energy bills should prioritize privacy over it, but the way I see it there is apathy on all levels of the society. I have friends who are very firmly in the top 1% of the British society and they also don't care too much about it, it's just yet another thing that they feel doesn't affect them so why worry about it. It's very different feeling to the one you can get in the US or in Germany or Poland, where even people who are theoretically not affected by surveillance laws are upset about them and will be very vocal about them.
Like I Said in another comment - on a personal level all I want is my friends, colleagues and family to say "this kind of thing is unacceptable in democratic society and I don't agree with it" instead of "meh I don't care".
