Yesterday, I blogged about Facebook’s desire to manage our WiFi connections and alluded to the need to access our location data for better advertising targeting.

Later, I came across this article from December 2018, which outlines the incredible importance of location data, and why Facebook creates an illusion of privacy controls, even as it hyper targets ads to its community. Aleksandra Korolova, Assistant Professor of Computer Science at USC also the researcher who wrote the article, notes:

The locations that a person visits and lives in reveal a great deal about them. Their surreptitious collection and use in ad targeting can pave way to ads that are harmful, target people when they are vulnerable, or enable harassment and discrimination.
