You need to send a lot of metadata unencrypted for decentralised e2ee to work.

Compare metadata leak between centralised Signal (which goes to impressive lengths to know as little as possible about you) and decentralised Matrix.

That's just not true, you can obviously use encrypted communications all along, even for discovery. Why on earth would you?
