The advertisers seem very chill despite the incident. Seems like they follow the maxim "any publicity is good publicity".
What's more weird is that the girls were suffering before the incident but are now very on board.
Next chapter will reveal why the girls aren't resisting, not really. Maybe they're just enjoying the attention they're receiving.
Whit these old Nagai's mangas a consistent continuety I'd say is just one of the parts of the overall madness. The characters only act the way the plot needs them for the story to go in the author's set way.
