it’s just the last drop in the bucket but, tbh, this shouldn’t come as a surprise from Andy seeing his past behaviour. Although I must admit that reading that manifesto from the CTO did make me puke so hard. As a developer myself (and yes, one that does use a mix of hand-written code and LLMs to some degree), seeing a CTO writing a manifesto like that one would basically mean to me: right, fuck these guys, time for a new job.
I’m glad that I’ve been this whole year transitioning all my important accounts to use a custom domain as their main email and seeing all this clusterfuck was the reminder I needed to cancel my Proton account.
My new provider is ForwardEmail, I was unsure between them or Mailbox.org but then went with the former as, since I self-host a lot of my services, I don’t need all the extra bloat. Tuta may be an option for some but for me was out of the options, I want to use Email client without the need of having to install an intermediary local proxy.
Regardless of what you choose to use now, highly recommend you get a custom domain. After that switching provider is as simple and changing DNS entries in your DNS registrar.
In your case I would start by getting my own custom domain, still bound to proton, and start moving my accounts to it little by little. Once you decide on a different provider you’ll switch your DNS records to it and everything will keep working (potentially also doing a backup of your whole inbox)
