It's not good for me that an email provider that supports that is undergoing dramatic changes, as an open standard that protects my privacy is more useful when it is used with more services.
I mean they are just shutting down completely. Notion is not coming up with their own E2E solution, they are just acquiring them to kill them, probably because skiff pages was a light competitor. I don’t know if it’s the founders or investors of skiff who pushed this decision, but it’s a sign of the shitty system either way.
I haven't used Skiff myself, but I would guess that that's what it was. Proton and Tuta also feature E2E encryption, and it's exactly how it works there, too.
It's not just a matter of learning, but also using a platform that supports it. If someone is part of the vast majority who prefer to just use webmail like gmail.com, GPG is just straight-up not an option, no matter how much they might be willing to learn.
