/I assume the thread is dead so..
Complaining on a form inherently lowers it's quality. As a rule Down-vote, Flag, or say nothing don't clutter up HN with posts that make for poor reading.
And yes, mass downvoting both sides of a thread is often better than getting in the middle of a heated debate.
At the moment there is no reason to believe either side and plenty of reasons to dismiss both, not as cranks, but at least as cranky.
