From the summary:
NASA requires the private companies to certify their spaceships are okay for humans to fly in (even if they're only for cargo). Thus SpaceX and other private companies have to pass the certification that their rockets are theoretically safe for humans.
NASA plans to build an spaceship (that is only going to fly cargo) and actually is only a practice run for another mission -- but since it holds the private companies to this higher standard -- it feels obligated to certify it's own unmanned spaceship is human-certified too. But human-safe certifying is going to delay the project and cost all kinds of money when they're only going to use the spaceship once and its not for humans anyway.
So apparently NASA must decide between hypocrisy and cost savings.
