The fact that you can’t use SMTP, which is a protocol that requires data on the server is not a vendor lock-in in any sense of the word. It’s a decision that depends on having that content e2e encrypted, because the two things are simy incompatible.
No, they aren’t. There are lots of ways to do e2e encryption on e-mail over SMTP (OpenPGP, S/MIME etc.). SMTP itself also supports TLS for secure server-to-server communications (or server-to-client in submission contexts) as well as header minimization options to prevent metadata leakage. And Proton decided NOT to use any of those proven solutions and go for some obscure propriety thing instead because it fits their business better and makes development faster.
Also the code for all Proton clients and the bridge is open source, and the bridge is essentially a client that emulates
The bridge exists yet, you can only run in certain devices AND it only exists until they allow it to exist. You don’t know if there are rate limits on the bridge usage and other small details that may restrict your ability to move large amounts of email around.
They also allow to export email content, which means I obviously don’t lose anything.
Decent providers will give you an export option that will export all your e-mail using industry standard formats such as mbox and maildir. Do you know what Proton does? They provide you a convoluted mess of EML files + metadata as JSON files that you can’t import to another service without some data loss. Same goes for Contacts and Calendars.
E-mail, contacts, calendars, notes and whatnot is one of the few truly open and truly interoperable solutions we still have nowadays. Protocols like IMAP, POP3, SMTP, WebDAV, CardDAV, CalDAV make it so you can have e-mail at any provider, talk to people from other providers and use any client application you would like - not like the bullshit that Whatsapp, Messenger, Telegram, Signal and others that that you can only communicate with people using the same provider.
Proton mail is so closed that you can’t even sync your Proton mail contacts / calendars with iOS or Android - you can only use their closed source mail client to access that data or the webui. Not even Apple, the most anti-competitive and closed company in the world, holds your contacts and calendars hostage - they allow you to sync with ANY CardDAV and CalDAV server and their iCloud service also supports those protocols so you can use it any 3rd party client.
Proton doesn’t respect the open internet by not basing their services on those protocols and then they feed miss-information (like the thing about e2e encryption being impossible on SMTP) and by using it you’re just contributing to a less open Internet.
