Is it even possible to use a google account without a phone number? Google (and about everyone else) demands them for tracking. I've steadfastly avoided giving out my number for most trivial things but it's becoming harder and harder. The recent dark pattern is to setup your account and then claim there was suspicious activity on first login so they need to verify your (brand new) account by having you enter a (completely new) phone number. Microsoft recently extorted it out of me by forcing me to convert my mojang account to a Microsoft account and then pulling the verification stunt. Twitter, facebook, etc all do this.

Another annoyance is if you enter a landline number most of these things just assume it's a cell and then ask you for the verification code that they just sent into the ether.
