The fact that they prioritized Helluva Boss (which does follow that type of storyline), on their own YouTube (which they have control over), whereas Hazbin was put onto Amazon Prime with only 8 episodes honestly is what I think caused it.
My gut instinct was to assume they had to agree to certain conditions to get onto Amazon Prime and the money from that is what got us Helluva Boss (which if you haven't watched that, it's so fuckin good)
