The article says this about the NSA: > It’s completely capable of engaging in domestic surveillance. And, indeed, it often does! So why would it need to purchase something it can obtain (more legitimately[?]) from its own dragnets and risk having part of its collection techniques exposed? I don’t think the NSA needs to worry about adversaries learning the technique of exchanging money for information. Hacking the data brokers would cause more potential exposure of proprietary techniques.
