This is hypertargeted advertising: different people see different info about same film, most get misled about its nature.
Same thing is now happening with political advertising:
Same candidates, but different individuals see totally different information about them. Most get misled about candidate's nature.
With a film you can stop watching when you find out truth, but after an election it's too late.
