This is straight up extortion. Either you start paying for a "free forever" service, or you lose access to every account you registered using Google OAuth with your custom domain email address.

You can migrate your domain and email, but you CAN'T MIGRATE your Google OAuth, and without that you lose access to all your accounts ON OTHER THIRD PARTY SITES.

I received the email on Monday. I, too, was in the boat of having friends & family using it. It was a mistake to trust their promises, but this was from back in the day of "do no evil." They said free forever, now ask me for >$1000 a year.

The insane thing is that almost everyone affected by this is likely to be highly technical, and in positions in which they have a say in how corporate spend happens.

I migrated away this week. I had to explain to my friends and family about this bait-and-switch, and have them all using Google Takeout. C'est la vie. I had not self-hosted mail infrastructure since I was a teeanger, but here I am again. Thanks, I guess?
