Just a quick look into Telegram and they use public API’s and not open source which is different and actually easier to send your data to a third party (not saying they are doing that but there isn’t really a way to know). Public APIs means that they let you use their services but you you can’t see the source code. This is closer to the ideas behind cloud than signal (just a quick look).
Fine. not all is perfect in every context. But ask yourself who is censoring?
I am not following what Dorsey is pushing others to follow especially when one of his IT security guys helped start up the app that he’s pushing and pros in the field say Dorsey’s people are fooling people into thinking their chats are private when they’re not.
I’ve used Signal and it’s fine but it’s tainted by a traitor to the USA so I am frowning on it.
