There's also a major definitional problem with the concept of "manipulating people for profit." Using the most broad definition of "manipulation," most people are okay with some forms of manipulation, and upset with others, although to me the distinction is not very clear.

A sign on a freeway incidating that a certain restaurant is 1 mile ahead probably wouldn't upset many people, but an advertisement for a mobile game might. Both are blatant attempts to manipulate people.
