True: here an interesting video about how using some services make you identifiable by connection maps. This affects also signal since you’re subscribed via your telephone number and people connect you through their contacts list. Additionally, metadata tell how often you talk to some people, what time, how many messages, etc. This shows to an attacker who are your main connections, etc.
So things are not about which kind of service you use (which app), but HOW you use it. The video really invites you to think about how these complex things work. Btw here’s the video:

Still leaks metadata, but given that you use your own server and proper e2e keys with enabled encryption, frequent re-keying and current room/software versions, it’s arguably more secure than most messaging systems.
Matrix / Element or XMPP.
We’ve had many discussions on here for why many of us think that signal isn’t secure.

Damn, very good video, thx for that.
This also affects Matrix or XMPP
It doesn’t, because neither matrix nor XMPP require the crucial piece of information linking you to your real identity: phone number, or email.
If we learned anything from the predatory ad industry, it is that you don’t need a piece of proof of identity to track and even deanonymize people.
