I personally do not care about privacy. I see no reason why I should.
It's just my opinion. I know other people do but please don't generalize.
Assuming that you don't care about privacy because you're apathetic, do you also not care about free speech because you don't say anything controversial? Do you care about your right to assembly even if you don't protest anything? As an extreme example upon which to build a baseline, would you mind if a neighbor had unmitigated access to watching you lounge in your underwear, take a shower or have sex?
Why do you not care about privacy? Do you feel that you don't need it because you have nothing to hide, or are you willing to sacrifice it for some greater good (e.g. terrorism etc.)? Are you merely indifferent or do you aggressively oppose the concept?
