Earlier quoted context omitted.
No one's performed a proper survey AFAIK, but the GDPR opt-out rate is very very low, which provides weak evidence. This is not evidence of numbers, but I have an existence proof in that I also personally know a lot of people who know and insist on not opting out.
Your proof is that you “personally know a lot of people who know and insist on not opting out”? That’s anecdotal evidence at best (aka not proof).
> This is not evidence of numbers, but I have an existence proof in that I also personally know a lot of people who know and insist on not opting out.
Most people I know would interpret that as "I know I'm not the only one because". After all, I specifically say "not evidence of numbers" and I also specifically say "existence proof". I find your response baffling.
