Most commercial Haskell is just boring CRUD, like with virtually any other language. There are some interesting projects like Hasura (a decently fast GraphQL engine), but something like Facebook is just a million times more prestigious, so that's what will always be brought up.

Feel free to link any write up making an actual case for this.
I know. It is something small that did not lead to more adoption and was five years ago.

I wasn't really recommending anything, I haven't even tried go, I was saying what seem to be reasons haskell isn't used in pragmatic scenarios, even by people who have invested a lot of time into it Still, cloudflare relies heavily on luaJIT and Love2D is built on it, meaning all these games have it at their core https://store.steampowered.com/curator/32659238/ The language is still lua and the speed is not disputed, so I don't think it is the same as haskell, since haskell still has a much bigger question of pragmatism and productivity.
