Here are two reasons you might not want to use Signal: Your contacts, your settings, your entire Signal experience is tied to a Signal account managed by Signal. Metadata—who you’re talking to, when, and how often—can still be collected and analyzed. Question everything.

How's signal compared to Element?

Also, is there a secure way to directly send messages to someone else's phone without the message having to be stored on a central server? As in they're only stored on the recipient device. Is that even possible with how the internet works and how packets are routed between networks? Even if the server has no way of decrypting messages by default, just having the encrypted messages stored there is a liability because your encryption keys can easily get leaked by malware running on your device, phishing, etc.

element keeps a lot of metadata unencrypted. but it is federated, you can choose the server that has access to it (deny federation for the room or set up federation ACLs if important to keep it there), and because of the former it's harder to just shut down.

signal doesn't, in theory they don't even know the recipient of your messages (but there's a twist in that part as I remember), but it is centralized around US servers. it is easier to shut down.
