This is about Haskell-the-ecosystem, not Haskell-the-technology. In that way I think it's a valuable contribution.
Stephen is a well known and respected part of the Haskell ecosystem, and has written many popular blog posts about the language and ecosystem.
Pact (a not complete Turing language for blockchain) is also interesting Haskell code to read and to learn from.
Namely Well-typed, FPComplete and Tweag.io who are all consultancy companies working on the Cardano project
An article saying "this sector of our community is bad and scamming retail investors" is already burning MAD BRIDGES and putting an enormous target on your back.
"Bob Smith and Joe Brown, specifically, are scamming retail investors" is going even a little beyond that. It's just not necessary.
EDIT: For the writer of the article, that is. We in the peanut gallery obviously want all the details, which is why a little detective work is often required in these cases.
The author mentions at least three Haskell-related companies, such as FP Complete, and says he wants to avoid naming specific people for the time being.
That's why the author rants about crypto and not about Haskell itself.
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.
And that would seem to be exactly what Stephen is complaining about.
The question in all of these cases is what specific bad influences the money can have on the software ecosystem and how community standards and governance can mitigate them. I don't really see a lot of answers in this article besides ill-defined ethical compromise of developers. I skimmed the book he mentioned (The Politics of Bitcoin: Software as Right-Wing Extremism) which sounds interesting but it doesn't really make its own case very well: half of the "extremist" citations are from anonymous online commenters and you can't go 2 paragraphs without straight up name-calling and ham-fisted guilt by association.
is an example.
