Nobody cares, what provider does. What matters is whether or not you sign a damn consent form.
Suppose, that there is a popular mobile App, written by Zhang Li Ltd. The App allows you to buy travel tickets, receive discounts in local stores and upload contents of your address book to it's servers. After a while you notice, that everyone uses it. Your local store no longer sells large amounts of grocery unless you make a reservation from The App. All train tickets must be booked by using The App. A bunch of local utilities stopped accepting payments unless you send them via The App. The thing is just so convenient!
One day you notice, that The App requires you to sign some "consent form" in order to use it's advanced features. A month later it threatens to delete your account if you don't "consent" (of course, it won't say so directly — "our ML algo detected, that you are Russian hacker! plz confirm your identity! account secuuuurity!" — that's how it will roll). The App is absolutely not connected to your ISP — it's authors just want to buy the data, that's all!
Reminds you of anything?
