I took part in the Whiteout crowdfunding and I think that their client was very promising, especially as there is still no Free Software client for Android that supports PGP&#x2F;MIME properly.<p>I also had the impression that it was just a lack of PR and good community management that is part of the reason for why Whiteout never achieved traction although it seemed technically superior compared to Lavaboom and other (at the time) more popular projects. They never seemed to have much of a presence in terms of discussions about PGP-enabled clients and could just have done more in terms of outreach. I am sad to see them go.
