Telegram messaging app proves crucial to Belarus protests
It's not surprising that every time Telegram pops up here, many comments miss the fact that Telegram has a great UX, a great feature set and also provides the kind of privacy protestors value, i.e., not having their phone numbers flashed to every random stranger in groups or to random channel owners whose channels you've subscribed to. With Telegram you cannot even do a phone number enumeration attack (this can be changed in settings) by adding phone numbers to your contacts list to find out who's using it.And nope, Signal doesn't make the cut for the above reasons because it exposes your phone number to everyone else. WhatsApp is the same in this respect. Neither of them prevent enumeration attacks (they may slow that down a bit, but not sufficient enough to protect against state actors).Wire and Element (Matrix) are comparatively better than Telegram, Signal and WhatsApp because you don't need a phone number to sign up and they also have end to end encryption for all chats (with Element it's a bit more recent). Hopefully more people can soon ditch phone number based apps that cause them to be vulnerable because of that vector.
