The article tells the story all wrong, if you listen to the interview Ed Fries says that their was 2 different Xboxes being worked by 2 different teams, one with Windows and one without, the one with Windows got the green light by Bill Gates and both teams become one and worked on that console, over time that console became more like the one that got rejected and didn't run Windows, so when the team had a 2nd meeting with Bill Gates and they told him it didn't run Windows he got angry...
