One of the differences between darkwallet and drk is the way the lead developers put their services out. Amir comes across as fuck the Man. Which gets more press but encourages the demonisation you describe. Drk has come across as being about privacy, not condoning or encouraging illegal activity. If people use it for that that's their problem. That privacy line needs to be reiterated as much as possible. The "noble" intentions as it were.
