If you have ethical concerns with this, but still love FP, just come over to OCaml. You get 80-90% of what you love about Haskell, and there is an established industry in many sectors. Big players here like Ahrefs, Jane Street, and, of course, Messanger and Facebook.
Tezos uses Ocaml; doesn't the same argument apply? (I don't agree with the argument, personally, and I'm a big fan of Ocaml... I just don't see how it deserves an "ethical concern" exception here.)
I am ignorant of the primary users of Tezos, but I imagine given it's low value relative to other coins, it isn't the prime target for black market deals, money launderers, and other criminals.
I love Tezos, personally, and think it's one of the more technically superior blockchains, and can see it having a better chance than other stable coins of having broad applicability to more than one or two industries.
I would agree. :) Is that the case with Haskell? The OP only says that "some of the very founding contributors to Haskell itself" are deeply involved in this.
You're right. Let's all abandon our frivolous jobs, live in a communal and sing kumbayah around the 100% eco-friendly heat source, congratulate ourselves for abolishing the evils of capitalism, and stand in our bread lines.
