i've just seen a comment in a post, in this very community, saying people trust signal because of missinformation (from what i could undertand).
if this is true, then i have a few questions:
-what menssaging app should i use for secure communications? i need an app that balances simplicity and security.
-how to explain it to my friends who use signal because i recomended?
-what this means for other apps in general?
The signal protocol is end-to-end encrypted, not even signal themselves knows what is being sent to what.

As I understand it, while they can't see the contents, the Metadata is still exposed.
Isnt the metadata also encrypted?
Yes
Your phone number is the biggest metadata you could possibly give (it means your real identity, including your current address), and signal has it.
phone number, IP, time of connection, duration of the chat, size of the encrypted chatlog, etc. might be useful for feds
