I'd say, the review was actually good for Josh, as it gave him very honest feedback, probably much more frank than what he heard from people in person.
People tend to say either "great, keep on going" or are very negative about a product, without being specific. It's easy to ignore the negative comments and write them off as 'hating'. I would venture that TC is an authoritative source, and therefore he took a hard look at what maybe needs to change.
