The claim says Proton Mail gave authorities information that allowed the FBI to identify an anonymous “Stop Cop City” protester using payment data linked to an email account. The claim comes from reporting by Joseph Cox published by 404 Media. 404 Media is a technology news outlet run by professional journalists who report on cybersecurity, surveillance, and digital privacy. The article references court records connected to the investigation, so it appears to be based on documented sources.
Looking for better coverage, the reporting explains that investigators identified the person connected to the Proton Mail account through payment information used to pay for the account. Although Proton Mail uses encryption and cannot read the contents of emails, it may still have access to limited account information such as subscriber or payment details.
Tracing the claim back further shows that the information comes from a court document related to the investigation of protests against the Atlanta police training facility often called “Cop City.” Because Proton Mail operates under Swiss law, the company responded to a legal request from Swiss authorities, who then shared the subscriber information with U.S. investigators.
Overall, the claim is mostly accurate but simplified. Payment data connected to the Proton Mail account helped investigators identify the person associated with the account, but the information was obtained through a legal process involving Swiss authorities rather than Proton Mail directly giving information to the FBI.
