"theoretically" being the operative word here. Most people don't. And if they did, they wouldn't be able to talk to anyone else without the metadata getting copied to that person's server. Probably okay if it's between two information security experts who operate their secure own servers, but in reality most people don't do that. This could be summarized as: Matrix offers a lot of easy ways to be less secure, Signal does not.
As for WhatsApp, I know they have paid or maybe still do pay Signal for their encryption. I believe Facebook Messenger did or does as well. I'm not sure what the actual implementation looks like and neither is anyone else, because it's closed source.
But that’s not what’s being said here. In this post people op is asking for federated Signal. People are saying matrix is just as secure. This is wrong and I am pointing that out so people don’t go thinking this is correct. Making misleading statements about the security of this sort of thing is dangerous.
