There’s a huge difference between “shows up beside” and “shows up on the same website” though. I don’t think GP was talking about showing ads next to porn, but rather whether unmonetized porn on a NSFW sub poisons the well for advertiser friendly subs.

My understanding is that advertisers had an issue with Nazi videos being monetized with their ads, not Nazi videos being on the platform at all. Obviously nobody wants to pay money to have their brand associated with that.
