ProtonMail was forced to log the IP address of a French activist and turn it over to Europol, according to a French police report that came to light over the weekend. French police sent a request to Swiss police via Europol and thus managed to force the company to hand over the users IP address and device details of the activist. Users have been pelting the privacy-hugging, end-to-end encryption-providing email provider with questions. CEO Andy Yen posted a statement about the incident to Reddit and followed up with a Monday blog post.”]
