So, I have a Threema license, but from what I’ve seen its encryption isn’t post-quantum. Signal’s encryption seems the strongest. I host my own matrix server.
Also, I kind of don’t care where the servers are or which provider it is. Everything is encrypted anyway.
Thank you for being one person in this thread that actually read and understood my comment.
A bunch of comments repeating “Signal is the most secure because I said so” was not helpful.
I just saw your reply to me and was about to say the same thing, but they worded it perfectly. And I did mention metadata as a key point in my original post.
