This is the exact sort of thing that allows people to think that things like Telegram are acceptable equivalents to Signal instead of disastrously poor imitators. It's a shame the discourse around secure messengers has become so polluted.

In the paper they were still able to cover 100% of US numbers for Signal and discover all of its users, but less than 0.02% for Telegram and discover only 908 of its users due to simple rate limits, how is Signal better at this exactly? On top of that the paper purposely chose unrealistic threat models and assumptions about privacy, as if letting other people know your phone number is somehow acceptable for privacy in the first place (it isn't and never was).

Rate limits are trivial to skirt with rented botnets. Some "Free VPN" apps allow inbound traffic from paying clients to be redirected out to the internet.

How is user discovery of Telegram at 0.02% worse than Signal at 100%? It isn't like they could possible get it any higher and Telegram's couldn't get much lower. People who know what they are talking about have been critical of Signals use of phone numbers since the start but Signal have always brushed it off as irrelevant.
