The publishers are fine; they are the devs who made Shady Lewd Kart:

They also published a ton of complete little indie games, some more notable than others. They basically just help small and single devs who have no interest or knowledge in the more mechanical process of publishing on Steam but aren't really full publishers in the sense that they promote the game and push it far and wide, etc.
It's just kind of to help other indie ero devs and to share presence since many people do click through to see a publisher's entire list so it's good to be on it for promotion.
However, they are pretty much open door so I don't think it's fair to hold them accountable for this dev's shittery.
