I’m not so sure I agree with that. I think there’s a legitimate question about how much “privacy” someone can have when so much of the allegedly “private” information is in the hands of a nameless, faceless corporate bureaucracy that employs tens of thousands of people.
At least it’s not in the hands of the omnipotent government and its myriad agencies.
If it’s considered a “willing” surrender by the consumer, there should be an opt-out clause. I don’t recall seeing any language to that effect in the contract I signed with the cellular service provider.
