I'm not sure what kind of algorithm they could use to find CSAM.

Pretty much every messenger is built around a central server. Tracing connections to that server is not without hassle but doable with government resources. Now, a Briar-Style P2P Network could work but that has it's own problems. Central servers are popular for a reason.

Decentralised messaging to the rescue!

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.
