After what happened to Telegram with the t.me domain, will Proton change any strategy? For instance, allowing logins from proton.me and protonmail.ch/com. A redirect can be cached by the browser. Maybe the other domains could have an autodetect system and not redirect to proton.me if it's censored or doesn't work. That could be easily achieved with some extra subdomains and could help fight some light forms of censorship.
