This is feedback from Proton Mail Team I got about this matter:
"Thank you for reaching out and sharing your concern. We understand why this story is alarming, and we want to give you a clear picture of what actually happened.
First, Proton did not provide any information to the FBI. The data was obtained by the Swiss Federal Department of Justice through a Mutual Legal Assistance Treaty (MLAT) process. Proton operates exclusively under Swiss law and only responds to legally binding orders from Swiss authorities, after all Swiss legal checks have been passed. This is clearly stated in our TOS and Privacy Policy.
In this specific case, Swiss authorities determined that the legal bar was met because a law enforcement officer had been shot, and explosive devices were involved during an incident in 2024. Switzerland has one of the strictest privacy frameworks in the world, and legal assistance is only granted in cases involving serious criminal matters.
Importantly, the only information that could be disclosed was a payment identifier because the user chose to pay by credit card although Proton accepts gift cards, cryptocurrency and cash. No emails, no message content, and no communications metadata were handed over. This actually demonstrates how little data Proton holds by design, our end-to-end encryption means we cannot access email content even if ordered to.
We hope this provides some reassurance. Please don't hesitate to reach out if you have any further questions.
I think 404 Media has an ethical obligation to provide Proton Mail’s response outside the article’s paywall. The word “Helped” in the headline is more sensational than stating that Proton “was required by Swiss law to provide...”
For readers who do not want to pay to read the article, the headline leaves incomplete context and creates a misleading impression of the story. That damages Proton’s reputation, and the missing context is only available if someone pays for the article, reaches out to Proton, or searches forums for substantive information.
