I don't think anyone's surprised by that. Our emails have literally been used to target ads at us since like 2006. Cell phone carriers are happy to mine voicemail, call logs, SMS, etc. in the hopes of finding a revenue stream that doesn't involve them having to do irritating work like running fiber to cell phone towers.

This leaves contact mining as the odd one out, but given how many apps want to see your contacts, you know that those are being sold by at least one of those apps.

None of this stuff has ever been end-to-end encrypted, so there can't be any way people expect it to be private.
