I can see why someone, maybe a "MBA biz dude", might a tad upset about someone who goes out of his way to piss all over the reputation of Rails. There actually isn't anything wrong about Rails having a cool reputation if it is going be to accepted in an ordinary. working business.
Without ever having him, I am pissed at Zed because he has good ideas and he makes himself so hated that his good ideas will not get a hearing in an organization.
I mean, if he wanted to storm the Bastille and launch the Ruby-powered communist dictatorship of the proletariat, then his screw-the-biz-people rhetoric would make sense. But he clearly wants to conduct business himself while somehow not getting a clue that reputation is a part of business.
