On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.
That would be for “yes” I suppose? Okay, okay - sorry, I don’t actually want to attack you anyhow or LMAO around - I just want to point out that it’s nice to imagine that “to be secure/to feel secure” is really not under control of someone’s privileged point of view. All what we’re talking about - just a reminder - that the question was about the MOST secure app. You’re accusing me of “trying to get people to use less secure systems” or “dissuading people away from Signal”. What can I say about it? I feel so deconspired that getting out is really the only option for me!
But maybe you could consider to really get in, huh?
