It's one of the many reasons why I don't like to associate my phone number with an account for 2FA and such... Or any other information that they don't need (like name, etc...).

I think that Google recently forced most accounts to give a phone number even if you don't use 2FA (probably for ID purposes). That's one reason why I like this service: https://www.emailnator.com/, instead of using my own gmail address for signups.

Anonimity is going down the toilet really fast in the US...
