Yeah I think you're totally right. The Author seems to be drawing a conclusion based on what is highly visible, but Matrix.org is both federated (what I think Thompson means by 'open') and supports e2e encryption. There's no technical limitation in e2e encryption patterns or federated messaging patterns that keeps them from being combined and used. Only that the default apps on iOS and Android are exclusively e2e or federated, but not both.
