when MullvadVPN, sweden, was not only enforced by courts but raided by police to turn over data they replied “what data?” And the raid turned up nothing. Even with physical access to the servers- the authorities with legal right to search left empty-handed. That’s planning for privacy, I would assume since Proton doesn’t do this for their VPN they only plan for privacy of activists to a certain extent in face of (unfair) court rulings.
