I’m still in disbelief having heard this for the first time today.
They did kill it for me. I was grandfathered into the G Suite software because I signed up back when it was free. Last year they turned around and said “we know we told you that, as an early adopter, you could have this forever; but now we’re kicking you out unless you start paying.”
And then they killed IMAP access (without oauth) moments later. Fortunately I was fast enough to set up my own mail server and copy my family’s emails, photos, documents, etc. out of Google. I haven’t trusted them since.
I’m actually quite pleased with what I’ve ended up with now. One of the features of the Postfix / Dovecot server I’m running now is that I have recipient delimiters - for example, if my email is hiding@aussie.zone, I can sign up for Mastodon with hiding+mastodon@aussie.zone, and everything they send me will be automatically filed into the Mastodon folder in my account. Additionally, I know exactly who is selling my data this way. It’s a great system and avoids the unfortunate predicament you currently find yourself in!
That’s the best part of Proton+SimpleLogin. I use a “different email” for every account for which I sign up. This allows me to know exactly who sells my info and who doesn’t, by which address starts to get spammed.
