I was worried about the project after Moxie left, but my concern abated over time.
Moxie is (or was, who knows how he's changed), by the way, a kind of leftist anarchist, the type I'd probably agree with one out of ten things on, the need for secure comms being one.
So a Board of Director government pawn who runs NPR and apparently failed freshman philosophy is not a concern to me. All that matters is the integrity of the app, which I currently presume -- by its open source status and by the audit of their encryption -- is not compromised.
