I have to say I agree with your sentiments, this guy is not worthy of our time.
I wrote about Medium and my take on the changes that were taking place. I wrote it with a thought that the article would prompt a response, as I hoped to create some debate. He didn’t engage as I thought he might. When I reflected I had felt goaded into writing it from things that he had said. So I was annoyed and realised that I had been taken for a fool.
There is other stuff going on that I find strange as well. He wrote an article calling out how bad Facebook was driving traffic to a Medium post, but then contradicted with opposing data.
I for one will be giving the guy and his group a wide berth from now on.
