It doesn't really have anything to do with the article though. It's just an anti-bitcoin article of which there are many.
The article here is about cryptocurrencies that pull in money through ICOs and that turn out to be fraudulent and that use Haskell and sprinkle some right wing politics on top. In the end the article doesn't really say anything if you ask me and I don't really see the link with Haskell. Haskell just has properties well suited for cryptocurrencies so it gets used more than certain other programming languages for this specific purpose. This seems more like the author disagreeing with consultants, who happen to use Haskell, that take on (according to him) dubious jobs.
