This sounds to me like WhatsApp just didn't participate very openly, not that the report had any factual technical issues with the service. Sure, them being very tight-lipped could be seen as a reason to worry about their security, although they've been technically open enough that I know a decent amount about their tech and stack. I even gave FreeBSD a fresh look after watching a few recorded sessions from their engineers. So... A bit of FUD maybe, backed by a not-as-open-as-the-EFF-would-like policy? (I am a card-carrying donor to the EFF, I just don't see the issue clearly.)
