Could you be more specific about these 2 issues you have?

I mean, of course the actual transit of the email from the sender to your inbox is out of their control, but after that client-side decryption is entirely feasible.

And what is wrong with hosting in Switzerland? Switzerland has very strong privacy laws.

Sorry, can you go into more detail? I don't understand your concern.

No OP, perhaps one could think they make such a big thing about security to try to attract lucrative accounts, which they then have backdoors into.

As you can't verify their claims, all you can do is trust. If you want end-to-end encryption you should be gpg encrypting every mail, not relying on the unverifiable word on a provider. Any provider worth its salt will know that, thus wouldn't actually advertise an insecure (as verify can't be done) system as a secure one.

I think you might be misinformed - their security is based on client-side encryption which is open source. See:

You don't have to trust any of their server code - you only have to trust that the JavaScript blob they send you is actually the same as the open source version. This is the same threat model as trusting Signal from the App store instead of side-loading it yourself.

As has been frequently pointed out, they could choose one account and serve that account a different webpage just once, and harvest their password in order to decrypt all their email in perpetuity. This would be a trivial change that would certainly go unnoticed.

I fail to see how this is any worse than any of their competition, which does server side encryption. At least with ProtonMail there is the chance of them being caught serving backdoored client-side pages - with server-side you would never know.

I feel like the hate is a case of people thinking not being perfect is worse than being average or bad.

If protonmail is billed as a pgp replacement, then people will think it is reasonable to use protonmail's encryption instead of 'offline' encryption, when that's not the case at all.

A version of ProtonMail with the application hosted locally, and no auto-updates, would fulfill your requirements I believe.

I don't really like them anymore (for similar reasons), but I don't know as I would put all other providers over them. Certainly, I think they're miles better than gmail.

I'll bite.. Please explain further
