I pay fastmail for a side business account but I've been thinking about buying a Google Domains "account" for personal use just so I can use a custom domain for free on Gmail. Identity theft is the sole reason I don't trust anyone else and Google owns my soul for that. In a matter of hours, just like your link shows, a hacker could reset the password for everything I have. With the data he acquired it could also be possible to circumvent TFA. Unfortunately even with me owning everything after the "@" I'm still locked to Google (I don't mind losing data) and they could freeze my domain if I do something wrong on Gmail. Could as in theoretically. Am I being over paranoid? Did this ever happened to anyone? Will I at least be able to reach a human on Google domains? Because I sure as hell won't be able to using a free Gmail account.
