Yeah, the author's opinion would be way more justified if Rails were an open-source project with thousands of contributors and not just the hard work of DHH himself in total isolation.
But no, you mischaracterize my position, which is that his opinion would be way more justified if he was critiquing someone who had led a failure, or if he had some really valuable insight that DHH didn't have, or if he had led something even more successful than what DHH has managed.
