The scariest part of this recent news is that TM Signal seem(ed) to be interoperable. People using TM Signal could interact with actual Signal users. How are you to know whether or not your groups have people using bastardized versions of Signal? Are things like Session interoperable with Signal?
What are the ones you’re after specifically?
I’m not totally sure signal has it, but I like the ram shredding and socks proxy. I know molly isn’t fit for everyone’s threat model but those two features I do like to see so I use it instead; I’ve not run into any issues with it.
