The problem here is the long-term tendency is to turn opt-in into "if you don't opt in you don't get any of our services".

Kinda like HIPPA medical privacy rights in the USA: when you go to a doctor, they'll hand you a paper for you to sign acknowledging you understand your privacy rights...then they hand you another paper for you to sign away those rights; if you don't sign both, you don't get any medical service. Imagine a not-distant future where if you don't opt-in to questionable services from Google, Apple & Microsoft, you're flatly denied use of any of their products - digitally ostracizing yourself from most of society.

Like not getting invited to parties and gatherings if you don't use facebook or not being approached for jobs if you don't use linkedin? We're already there.
