Why use two different apps? I only use Signal, and have gotten so many friends, coworkers, and family to use Signal.

The encryption method they use was made up by them, and the chats aren’t even end to end encrypted by default. Which I would argue is a larger red flag.

I wouldn’t say USA has all the encryption keys, but the fact that it is actually possible to have a backdoor is reason enough for me to not use it. Signal complies with all search warrants, giving all the data they have to law enforcement. They have never given any data to law enforcement, because they do not have access to it. Telegrams approach is to simply to spread the data to several servers in different countries, so if law enforcement wanted access they’d have to submit requests to each country (some of which wouldn’t comply).

If you have a safe, but cannot open it, do you own the contents inside? Signal has no way of accessing your data, I would argue they don’t own it.
