Why would you want another year of their software for free? This is their second screw up (apparently they sent out a bad update that affected some Debian and RHEL machines a couple years ago). I’d be transitioning to a competitor at the first opportunity. It seems they aren’t testing releases before pushing them out to customers, which is about as crazy to me as running alpha software on a production system.
I’m sure you have reasons, and this isn’t really meant to be directed at you personally, it’s just boggling to me that the IT sector as a whole hasn’t looked at this situation and collectively said “fuck that.”
As someone who has been skeptical of Proton and avoided their services because it seemed too good to last (or be true), this really boosts my faith in them.
Not saying I’m going to stop self-hosting my own mail, etc. or become a customer tomorrow, but I’m much more likely to recommend them to friends and family who ask, and will absolutely keep them in mind for myself if I ever do have a need.
