The reality is that the privacy policy will almost never be a determining factor in whether somebody will use a service. The Facebook haters on HN were never gonna use a Facebook product anyways, regardless of what the policy said, and the same goes for the people that are happily using threads now. Does the privacy absolutist who refuses to do anything outside of a VM behind Tor exist? Of course, but not in any meaningful amount for it to matter.
The people closely reading terms of services and opting out of arbitration provisions or whatever are wasting their times with busywork. It's doing work that feels meaningful and feels like giving it to the man without actually accomplishing much of anything.
