If people didn’t care, privacy wouldn’t be a marketing tool and things like “App Tracking Transparency” that Apple added to iOS a while ago wouldn’t have worked so well.

Also, do you close your door when you go on the toilet, or go around telling everyone your credit card details?

Things like these don’t come from ignorance of privacy, but rather services are explicitly designed to lock you in and have unbearably long privacy policies and ToS agreements.
