Exactly this. The article is not about the Haskell language itself -- i.e. not a rant about technical issues -- but about its community and consulting companies getting (allegedly) entangled with crypto businesses. "Making a deal with the devil".
That's why the author rants about crypto and not about Haskell itself.
I am not sure what is "alleged" about Haskell consultancies getting cryptocurrency money. It is pretty easy to confirm. Both Well-Typed and FP Complete got money from Cardano and posted to their blog what amount to advertisements for Cardano. Google a bit if you care.
"Alleged" as in "the article claims this, but I personally haven't double-checked it so don't want to make my post sound as I myself were sure this was the case". "Alleged" doesn't mean "unfounded".
I've written enough comments on HN to know that if I don't word it this way, someone will inevitably start arguing with me as if the assertion was mine.
That's why the author rants about crypto and not about Haskell itself.
