I would only ever suggest matrix if you’re running a private self-hosted instance that is NOT federated, which you can do even easier with Signal anyways.
Looked into anarc blog. What there wss said about Matrix can be said about SMTP and probably XMPP. To do GDPR you need to know every server you have sent message to. And compared to IRC defaults(forward and remove) anything will look like GDPR nightmare. GDPR was not designed for federated(like matrix and activitypub) communications and especially wasn’t designed for peer-to-peer communications.

That’s fine, but why?
It is a privacy and GDPR nightmare, basically all federated services right now are.
