Proton Mail Helped FBI Unmask Anonymous ‘Stop Cop City’ Protester

A court record reviewed by 404 Media shows privacy-focused email provider Proton Mail handed over payment data related to a Stop Cop City email account to the Swiss government, which handed it to the FBI.

404 Media
@404mediaco An extremely misleading headline. It was the Swiss government that ordered Proton to hand over the data which is not up to them to decide. The fact that the article content is paywalled also doesn't help.
