They advertised that they dont log IP addresses while they were logging the IP address of at least one user.
Then they got caught doing this and did a PR campaign to explain why.
This is duplicitous, false advertising, and lying until they got caught.
Further, due to the nature of warrants, the tech involved, how investigations work, relevant laws blah blah... this means that potentially any user could be subpoenaed by the Swiss gov, and ProtonMail would give out their IP without ProtonMail telling said user. This means any user based in a country that has roughly friendly relations with the Swiss gov is at risk.
I thought a whole point of safe and secure email services is that they are also safe and secure from governments? Most of them are marketed that way.
I dont know about yall, but if they even have the organizational and technical capacity to provide the info they did, they are a piss poor 'private and secure' email provider.
