Eh I guess without any context then its not a very useful blog post. I'd still like to see some links or an attempt at verifying some claims. Even a byline with his industry experience would help.
There are links scattered throughout, but part of the point of this post is that no one is really talking about this issue at least at the depth it deserves, so understandably it's light on references. In this case, I'd treat a lot of this as an original source.
There are thousands of 'publishers' like this - I don't believe he's qualified to claim the industry is broken. He can't see anything from a macro perspective.
Given that he has a wiki page https://en.wikipedia.org/wiki/Josh_Marshall, it's pretty obvious that you're not interested in doing the slightest bit of research into the subject that you're criticizing.
