I think it has to do with his red Dust blade. Adam, Raven, and Qrow all have red blades in their weapons, and they're all shown to be very powerful and feared in battle. Since Qrow is a good guy, he seems to be more conservative with it, only showing the red blade in his weapon's scythe form, while Adam and Raven, with more questionable morality, flaunt it.

I think they can cut through or do more damage Aura, which makes them very taboo, since anti-Aura weapons would serve no purpose against the Grimm, and exist only to be lethal to humans. This would explain why we've only seen them in the hands of a major villain, a mysterious vigilante, and Vale's top spy.
