> A very small fraction of logins get the CAPTCHA challenge. We, and other services, face unrelenting brute force attacks on our login endpoints. If you are seeing a CAPTCHA on login, chances are that something about your connection is suspicious to our system.
IME CAPTCHA will make your internet use unbearable if you a) are from a non-Western geo-location or b) you use a VPN. VPNs like the service you provide, which a fair number of your email users probably avail. It's fair to say a smaller number of "internet users" get CAPTCHA hell (which i also doubt), but I wonder if the ratio of Proton* users actually skews the other way.
