"Urgent: Sign in to your Google Account if you want to keep it"
But then it doesn't matter if you log in with the correct username and password and receive the PIN via your email. This is isn't enough. Unless a phone number is somehow added to the account one gets,
"You can’t recover your account at this time because Google doesn’t have enough info to be sure this account is yours."
This is despite having all information ever associated with the account. Unless that account has a phone number it will be deleted. This is a very shady dark pattern by Alphabet corporation.
We've fallen so far from the days when the retailer let you just have the game you bought and then they were out of the picture forever.
Advertising company (Doubleclick [1]) wants phone numbers to better target ads. No surprise there.
[1] The company currently calling itself Google is not the same Google as yesteryear. In 2008 Google purchased Doubleclick, and what happened is that the advertising rot from Doubleclick ate Google from the inside out. What we have now calling itself Google is actually all the evil that was Doubleclick, only calling itself Google. That's why the Google motto no longer includes "Don't be evil".
So will they also delete inactive accounts that have no phone number, but one or more phone-less 2FA methods associated?
