Leave? I never joined. I’m still with aol. :)
I’m still using pacbell.net, my first and only email address. I bought the family surname domain for a few years in the early 90s, but never used it, so I gave it up. Some guy with the same family name in Germany swooped in and snatched it up and renews it every year.
I keep thinking about switching to Proton Mail as pacbell disappeared years ago and AT&T does an awful job keeping it running.
