Well I'm sure someone has engaged him before so I don't think I would be particulary productive. Seeing his page there are serious problems or misunderstandings with some of the sources he uses, regarless it's also very easy to criticize something and far more interesting to find solutions, you can critize the current decentralization tech much like you could easily criticize and dimiss this internet thing in 1984. I was just genuinely curious about his motivations. My example with angular is that even though I really don't like it, I wouldnt want to waste time criticizing it or stopping people who want to advance it.
