The second one is such a horrible thing that I wish it was blocked by the OS. Stop giving apps access to your entire contacts!
I did not consent to those companies knowing my phone number, name, and likely other information!
But you clicked a little button that they can so its completely fine! \s
That is likely my single biggest pet peeve of the current state of tech is other people being able to consent to MY information being gobbled up just because they clicked a damn button.
