When someone spouts big talk like "start doing things right. Since you don't know how, you have to hire someone like me and give that person lots of autonomy, but it can be done" and all they're known for (please correct me if I'm wrong here) is writing a lot of text on HN, I don't think a little snark is out of line.
I get that railing against unsympathetic targets like big corporations makes for entertaining reading, but I don't think that actually qualifies anyone for the job he was describing.
