I was super-impressed with Acton's creation & principled stewardship of WhatsApp, but with regard to Signal, he's been essentially invisible since the initial announcement of his donation/involvement. His name only appears twice at the `signal.org` website: https://www.google.com/search?q=site%3Asignal.org+Acton https://www.google.com/search?q=site%3Asignal.org+Acton His name doesn't appear in any recent Signal news – such as this, about the foundation being ready to take donations. As of April, he was supposed to be speaking at the 'TechCrunch Disrupt SF' conference that happened earlier this month – https://techcrunch.com/2019/04/03/whatsapp-brian-acton-disrupt/ https://techcrunch.com/2019/04/03/whatsapp-brian-acton-disru... – but he wasn't on the final schedule/speakers-list and I've seen no followup coverage indicating he actually spoke there. It'd be good to know what his actual involvement is, before transitively having confidence in Signal based on Acton's experience.
