Hah, if only that were true. That scandal would be so big that it would likely threaten Facebook's entire business as it would lead to lawsuits and Justice Department investigations. Facebook has a privacy policy and is required to abide by it. No manager would ever greenlight a program that actively violates that as they would get canned on the spot and there's very little benefit to them.

Don't get caught up in conspiracy theories. Facebook is actually really constrained in how much "evil" stuff they can do without you knowing.
