> Signal does not have any metadata except account creation and last-seen timestamps

I hate the way Signal sells it, like there is zero trust involved and everything is solved by some magic encryption. There is a lot of data the Signal could store, like who is receiving the group message you just send to, that is only guaranteed by their server's source in Github (they could be hosting another thing and you will never know). That said, Signal is still much superior in terms of metadata protection, like the sealed sender feature for direct messages which will take time to arrive in Matrix [1]. I just wished they were more transparent about what they can't store and what they can store but is not storing.
