I was surprised how much of what the company says about their service is apparently lies. Of perhaps even greater interest is the CIA connection. Protonmail is based in Switzerland, and there was a pretty detailed Twitter thread by AnonymousSage (gone from Twitter, now on Gab, don't know if he has recreated his threads there) showing how Switzerland is likely the true home of the CIA.

There appear to be some blog posts which may contain the same info, but I can't find sage's thread, since he's gone off twitter now.
Anyway, on a kind of side note: not knowing the compromised state of protonmail, I opened an account with this user name, and used it to create a Gab account with this username.
When I changed my pass on the gab acct most recently after the tranny hack, I forgot it, and so asked them to send a create new pass link to my protonmail. But there was a half hour delay in receiving that email, and the token expired.
This happened three times! And now when I click the forgot pass link on gab, it never arrives in protonmail. Is this intentional on the part of protonmail? I hardly posted on gab, just used it to browse posts of others, so no great loss I guess, but fucked up all the same!
Alternative anonymous mail provider?
