De-platforming these end to end encrypted apps is probably getting backed by fed gov because they cannot snoop everything as they do on all other communication apps
Telegram supports (not by default) end-to-end encryption in some contexts, but I wouldn't want to call it an end-to-end encrypted app lest someone get the wrong idea and try to use it for security.
Yeah, telegram is a pretty neat instant messenger based social network but it shouldn't be described as a secure messenger.
