What he did with messaging... So he will centralize all of it with known broken SGX metadata protections, weak supply chain integrity, and a mandate everyone supply their phone numbers and agree to Apple or Google terms of service to use it?

The issue being there's not really a credible better option. Matrix is the next best, because they do avoid the tie-in to phone numbers and such, but their cryptographic design is not so great (or rather, makes more tradeoffs for usability and decentralisation), and it's a lot buggier and harder to use.

Or, he took a barely niché messaging app plugin (OTR), improved it to provide forward secrecy for non-round trips, and deployed the current state-of-the art end-to-end encryption to over 3,000,000,000 users, as Signal isn't the only tool to use double-ratchet E2EE. >broken SGX metadata protections Citation needed.

This is what F-droid does (well, I suspect most apps don't have reproducable builds that would allow 3rd-party verification), but Signal does not want 3rd-party builds of their client anyhow.

Yeah, whatsapp uses the same protocol.

Just WhatsApp. Moxie's ideas are used in plenty of other messengers. The context was "what Moxie did for the field of instant messaging".

They could still figure out a way to attest their builds against source.

It’s exciting to hear that Moxie and colleagues are working on something like this. They definitely have the skills to pull it off.

Few in this world have done as much for privacy as the people who built Signal. Yes, it’s not perfect, but building security systems with good UX is hard. There are all sorts of tradeoffs and sacrifices one needs to make.

For those interested in the underlying technology, they’re basically combining reproducible builds, remote attestation, and transparency logs. They’re doing the same thing that Apple Private Cloud Compute is doing, and a few others. I call it system transparency, or runtime transparency. Here’s a lighting talk I did last year: https://youtu.be/Lo0gxBWwwQE
