>My credit card issuer locked out my Visa after I bought some clothes from a French web site. They didn't notify me and I didn't find out until my card was declined at a restaurant, which was fairly embarrassing.
>People get locked out of their financial accounts all the time and despite persistent rumors to the contrary, it is way more likely that your bank or credit network is using a blackbox AI to do it, with a shit vendor like Feedzai.
That's not being locked out of your account. You weren't able to charge but, should you have had the need, you would have been able to log in to your Visa account online to diagnose the issue. You would have also been able to dial a number or email for support. With Google, you are indeed locked out of your account and every other account you authenticated with using your Google account. There is no phone number or email address. There is no support. The scenario you bring up pales in comparison to Google's behavior.
