“We care about your privacy.” is also a real joker. Those boxes often provide no “opt-out all” button and force you to “object” to “legitimate interests” one-by-one even if you do “opt-out”.

Why do companies even bother writing that?

They clearly don't care, if they did that box wouldn't even be there.

Sites like Imgur are the absolute worst. "We care about your privacy" and presents you with a list of 1200 companies they share information with.

Is there any way to auto opt-out of these sites? Like an adblocker, but for these privacy pops?
