"Lots of people told me about Protonmail, I tried it, and discovered it was cabal years ago... The only company I have consistently promoted is Orangewebsite.com which, when THAT gets shut down it will be because everyone else is already toast."

ProtonMail, a hosted email service with a focus on end-to-end encrypted communications, has been facing criticism after a police report showed that French authorities managed to obtain the IP address of a French activist who was using the online service. The company has communicated widely about the incident, stating that it doesn’t log IP addresses by default and it only complies with local regulation — in that case Swiss law. While ProtonMail didn’t cooperate with French authorities, French police sent a request to Swiss police via Europol to force the company to obtain the IP address of one of its users...

...French police received a message on Europol. That message contains details about the ProtonMail account.

Here’s what the report says:

The company PROTONMAIL informs us that the email address has been created on … The IP address linked to the account is the following: … The device used is a … device identified with the number … The data transmitted by the company is limited to that due to the privacy policy of PROTONMAIL TECHNOLOGIES.”
