I like the idea of community-driven man pages, OTOH most of them were of quite a low quality (quite some time ago) and gave examples that were bad practice. And, at least for everything POSIX the man pages have really well-written and thought out examples.
Well, yes and no. Matrix is a protocol, yes, but it manifests as a cloud messenger, meaning all the messages are stored on all servers taking part in the conversation. Yes, if you use E2E, these messages are encrypted ā but thatās by far not enough for these conversations to be considered āprivateā.
So no, keys matter much, but they arenāt everything.
What we need (and they seem to be working on this, as they do actually acknowledge the weaknesses of Matrix!) is true peer-to-peer conversation.
