Want to bet that any messenger service that requires your phone number to register and id you on their network is compromised?
For those interested, watch this interview of the Telegram founder by the US right- media as it offers an interesting insight about the politics and competition behind these messenger / social networks - https://www.youtube.com/watch?v=1Ut6RouSs0w ... (And this is, by the way, the original source of the story - https://www.city-journal.org/article/signals-katherine-maher... - which also seems to be US right- media. Looks like a concerted Republican / Trump followers attempt to have their flock use Telegram now.)
