I have re-read the blog post and I can't find what you mention.
The blog post is basically telling us that cryptocurrencies and its leaders are a giant scam and they don't contribute anything of value to society.
Your interpretation is very generous if you ask me. A blog post with that angle would be interesting to read though. It would have more to do with the Haskell ecosystem than this one and it would be good to have that discussion if the cryptocurrency influence on the ecosystem is too big.
