I don't think people in charge of what gets on amazon prime are capitalist ideologues who smell leftist ideas and purge them on sight to ensure the status quo remains intact in the long term

It's incompetent executives who look at spreadsheets and focus groups to tell them what treats will make them the most money next quarter, they probably have no idea that The Boys contains leftist ideas, they probably just see it as "woah what if super heroes were evil"
