Using 2FA phone numbers for targeted advertising. One of the dumbest ways ever for a company to abuse its users’ trust. Take a bow, Twitter. And have a $150 million fine too.

I can’t think of any other company which would be so dumb as to allow advertisers to target individuals by exploiting phone numbers only shared for the purposes of 2FA.
Oh, hang on. Yes, I can.
Facebook.
TL;DR : USE 2FA wherever possible. But do it with an authenticator app or a security key rather than a phone number if you can.
