Thank you for keeping the Persona dream alive. It turns out that being open source wasn't sufficient for Persona to be able to be continued by a third party: we accidentally baked in some intractable centralization, and the code was too much of a mess. Moreover, I'm not sure that Persona's proposed architecture makes sense outside of a browser vendor.

I just gave a keynote on this exact subject at linux.conf.au; video should be online in a few hours somewhere under https://www.youtube.com/user/linuxconfau2017/videos?shelf_id.... The title is "Designing for Failure."
