I haven't heard that proverb before, and yes, I can see how you can apply it. I think that maybe this is being overanalysed slightly, I don't mean to apply a quota to anyone. I hardly think this qualifies as a 'cult'.
I just think that overall very little of what DHH has to say is praising or supportive of anything. Yes, that's judging the person, but only after I've judged the messages for the several months I was reading what he had to say. It's mostly things like this - "Forbes isn't exactly known as the pinnacle of journalism, but their latest piece on Salesforce was too much" - I can make my own mind up about Forbes' quality of journalism. He states that as a fact, not an opinion.
