From a privacy standpoint, do Signal or Matrix (via Element) have any advantages over the other?

Signal seems to have better audit records (from what i hear) and leaks less metadata then Matrix does BUT it is a centralized service and its tied to cell numbers so there is some inherent metadata risk there as well.

Long and short I use both lol

    The only metadata signal has is your number and when you last accessed the app. All the other data is encrypted

    When messages are sent and the traffic does have to physically get to the recipent. That is to say you would need to schedule sends (which it can do) and use something obfuscate the network trafic (i.e. Tor, a VPN) and the reciptent would still be exposed in that case.

    So if Signal's server was compromised and network traffic could be analyzed you determine who was sending to who and at what times. This could be leveraged for more targeted attacks or simple censorship.

    Signal and matrix are used for different things. Matrix is a Discord-like whereas Signal is a Whatsapp-like.

    Matrix is clunky in my experience so I prefer to use Signal.
