And what advertising is that precisely? No data ( emails, passwords, drive files ) were shared with the authorities. So the data is still secure and private.
As far as I can tell they haven’t falsely advertised.
I’d give them bonus points for transparency ( publishing how many court ordered subpoenas they receive on a yearly basis ) compared to other companies that don’t.
Other companies which are prominent in the privacy/secure email scene face similar issues.
I think you’re mixing up anonymity with privacy. It can definitely be more anonymous, but you would need to take steps for that yourself ( Tor, VPN, … ).
