Your "zero-access design" claim is a lie, you absolutely can see account content when emails arrive from non-Proton users, which is the majority of email traffic, But I'll get back to that in a minute...
@phrack has been around longer than Google, and are OG's in the hacking scene that predate even social media wtf did you think would happen?
You're CEO responded earlier, so there 100% was a 'chance to respond' so that's another lie, also it's not like all this came about 10 minutes ago.
The CERT excuse is hollow, CERTs issue advisories, they don’t order account suspensions as they are not law enforcement. By you're own admission you killed the accounts because CERT complained, and that's even worse, IF you couldn't see the context of the messages.
Proton chose to act on an unverified tip and then tried to frame it as an unavoidable mandate.
You scan, filter, and process plaintext messages before encryption, giving you complete visibility into correspondence from Gmail, Outlook, and every other external provider.
Your spam filtering system literally requires reading message content to function, proving you have routine access to user communications. Stop hiding behind "zero-access" marketing when you demonstrably possess the technical capability to read most emails passing through your servers, the same capability you just used to identify and disable accounts based on their activity patterns.
Proton sells “privacy” and kills accounts on a CERT tip. A complaint ≠ court order.
Proton is Swiss, CERTs are advisories, not subpoenas. They suspend first, litigate never.
They admit thousands of compliance actions.
If they wanted to fight it they could, in turn forcing a court order. They didn’t. They folded, same as ALWAYS.
