OK, I get it, this is a long time coming and you've been really good at communicating about it.
About 6 weeks ago I stopped using GMail for my personal domain, billbliss.net, and started using Exchange. This was triggered by Google ending support for their legacy free plan. They have since backed off from that a bit, so I could go back if I wanted to.
GMail's spam filtering and classification are the best I've found, so I'm still using it as my main mailbox under the covers (mailto:email address removed for privacy reasons).
I've always used POP3 access to pull emails into that account, and that stopped working yesterday when my tenant was chosen to disable basic auth.
I wish Google would add Oauth2 support for POP3 access, but I'm not going to hold my breath.
All I can think of as a workaround is to suck my Exchange email into some other temp storage service that supports OAuth. Clunky, but it would work, I suppose.
Any other bright ideas? I'd rather not switch back to GSuite for billbliss.net, though that would be far simpler.
