That's an unfair accusation.
He nailed colours to the mast in the past and it's not turned out as predicted, but I don't think he's set out knowingly misleading peaple.
The only reason the errors are blown up is because of his online presence. If a person with 50 followers said it, nobody would care.
Personally, I listen to his pods, I read his blog posts and occasionally check his Twitter. Some I'll agree with, some have me scratching my head.
As with everything else online, I'll take most of it onboard with an air of caution. Nobody is right (or wrong!) all the time.
