In that article he states:
Yes, the rocket that thundered aloft from NASA's Launch Pad 39B sure looked like an Ares 1. But that's where the resemblance stops. Turns out the solid booster was – literally – bought from the Space Shuttle program, since a five-segment booster being designed for Ares wasn't ready. So they put a fake can on top of the four-segmented motor to look like the real thing. Since the real Ares' upper stage rocket engine, called the J-2X wasn't ready either, they mounted a fake upper stage. No Orion capsule was ready, so – you guessed it – they mounted a fake capsule with a real-looking but fake escape rocket that wouldn't have worked if the booster had failed. Since the guidance system for Ares wasn't ready either they went and bought a unit from the Atlas rocket program and used it instead. Oh yes, the parachutes to recover the booster were the real thing — and one of the three failed, causing the booster to slam into the ocean too fast and banging the thing up.

But he goes even further:
Here's my plan — and yes, I am a rocket scientist — cancel Ares 1 now and the version of the Orion capsule that is supposed to fly astronauts back and forth to the International Space Station. Instead, unleash the commercial sector by paying them for transportation services to the station.
