But commenters are taking evidence of how this guy runs his business as evidence that that method is effective. Shouldn't there be comments pointing out if this isn't effective?
Not really. It will always be easy to look at something from the outside and point out all the ways it should or can’t work or could work better. The systems and people involved are usually much more complicated. The world also owes itself more compassion. “Thousand foot” criticism lacks compassion.
People pay me to do exactly that. Come in with a fresh, unbiased view on things, look at how stuff works and what could be improved.
It's not about telling people that everything they've done before is BS but if there are things that are not working well, just tell them.
