All of that said - I'm replying to this message and not the other because there is one use for secure e-mail that may make a difference: DeltaChat. Deltachat uses autocrypt which includes your public key in headers. With autocrypt in place, Thunderbird can still read DeltaChat messages.
I'm not sure if DeltaChat will ever take off in large numbers but it seems like a decent option for secure chat/IM.
This is so ridiculous. I have to log in to a dozen different sites to download documents. And those sites are 2FA secured, so I have no means to automate. Of course these companies never heared of (REST) APIs. - This is such a step backwards.
I know it's for liability reasons, but annoying nontheless
Well, since everybody is using Gmail or Office365 anyway, encrypted email is kind of pointless, no?
