Based on what @adam said about Cuties on show 1277, I think that Netflix probably anticipated the reaction over the movie and may even have fed it. Based on his and @Johncdvorak's conversation, what's actually in the movie isn't really worse than the TikTok accounts of bad teens, but it was certainly advertised as something filthier.
Not that this makes Netflix any better, it certainly shows them as exploitative, but more of their audience than of kids.
