You can do that kind of advertising without collecting this much data and creating psychological profiles on every user (think: Coca-Cola). And even if I like something seeing it repeatedly online just annoys me more than it inspires me to buy their stuff.

This is classic marketing and it doesn't require the level of privacy abuse that Facebook has been trying to justify.
