What are your sources here? Aside from Proton VPN being no-logs already being proved in court, Proton has third-party audits to back up their no logs claims: https://protonvpn.com/blog/no-logs-audit
They haven't cited any and likely can't. As an end user at the end of the day I care about real-world track record. Proton has not been able to comply to real-world requests over several years.
While theoretically there may be more secure approaches you may also be introducing new dangers as well. Eg; paying for a VPS with an anonymous coin doesn't mean your VPS provider can't deanonymize you or comply with a warrant. You need to make sure every single link in the chain is foolproof. That's way more error prone.
IMO a proven legal track record is in a way more valuable than unproven theoretical flaws (if you can even call them that).
- is opt-in. You must actively choose to use this feature
- is open-source
- uses an open-source model
- does not use your data to train the model
- doesn't break existing zero-access-encryption
- runs locally on supported devices
- can be run on a Proton-provided no-log server if you choose to
From my understanding Scribe doesn't do anything unless you enter a prompt. And before that you have still have to choose between local or server side before you can even use it.
They only have to comply with Swiss courts, but they're pretty up front about what they can and can't do, including suggesting Tor for anonymity, and the difference between Mail and VPN in Switzerland (VPN is no logs).
"the identity and location of the activist was already known to the French authorities. The fact that Proton Mail was not able to hand over any messages even under legal order proves that our encryption works, and very likely of great assistance to the activist in this case. Had they been using any other email provider, the outcome would have been very different.
"we also provide an onion site for anonymous access (we are one of the only email providers that supports this)."
They also updated the blog:
"Update: In October 2021, Proton won a Swiss court ruling that email services are not telecommunications providers. Consequently, email services are not subject to the data retention requirements imposed on telecommunications providers and are exempted from handing over certain user data in response to Swiss legal orders."
