afaik Romero was fired for not working. Cubicle walls came down because Romero was playing Doom on the clock instead of making the game(his form of protest for not making an RPG or something). If you look at Quake code most broken/lazy stuff was done by him. Example https://www.youtube.com/watch?v=DEkjDkr0Qmc
AFAIK, Romero was a bit full of himself at that point in time seeing himself as a godly game designer. He then went on to start his own company and build the RPG he wanted, Daikatana, which was late, over budget, and flopped big time.
