Andy Yen's values are incompatible with Proton's mission. He advocates for poor security practices, supports fascists, and he verbally abuses his subordinates. As such, I can no longer in good conscience continue to financially support a company with such terrible leadership.
Unfortunately for me, my subscription just renewed last month on a multi year plan, but it does give me time to browse for and experiment with alternatives.
If you're able, I encourage you to do the same and cite Andy Yen as the driving factor for your decision. We can't let these tech bro fascists destroy what little semblance of privacy we have left.
If you use an email alias software like addy.io, email basically becomes ephemeral. Change providers whenever you want and just change the forwarding address for the alias.
Also helps with internet hygeine to have a different random email for every account.
Since nobody mentioned it here yet, Mozilla has a similar service called Firefox Relay and it's super straightforward and a joy to use. I used it to create an alias for every service (some 400+) that has my email address and now I can just block emails going to any alias of a compromised account and set up a new one.
Unfortunately that just moves the single point of failure to the aliasing service.
I use SimpleLogin, which was bought by Proton a while back.
Email by its very nature has several single points of failure, but having the ability to use aliases to move email around to different mailboxes and even entire services is still neat. You can present the world with your own domain, while routing the resulting email anywhere.
I'm basically doing that with my domain. Have a vaguely corporate sounding domain, and just generate random firstname.lastname per service, on a catch-all address.
