Same for me, just in the process of updating my mail adress everywhere again right now.
My renewal was just coming up and I also couldn't justify it. I've switched to a personal domain with my E-Mail and use Infomaniak for mail, calendar and cloud storage and Keepass as my password manager. Positive side effect, I only pay half of what I've paid for Proton.
They also made a patch with that album title on a guitar, I've got it on my battle vest! And the album is great as well
