One program exfiltrated user data without user knowledge, in an effort to elevate some in power an attack others in power. The other program exfiltrated user data that the user explicitly opted in to, likely in an effort to expose the uneven enforcement of ads, among other things. >The personal data of up to 87 million Facebook users were acquired via the 270,000 Facebook users who used a Facebook app called "This Is Your Digital Life." By giving this third-party app permission to acquire their data, back in 2015, this also gave the app access to information on the user's friends network; this resulted in the data of about 87 million users, the majority of whom had not explicitly given Cambridge Analytica permission to access their data, being collected."[1] >When Facebook said Ad Observer was collecting data from users who had not authorized her to do so, the company wasn't referring to private users' accounts. It was referring to advertisers' accounts, including the names and profile pictures of public Pages that run political ads and the contents of those ads.[2] 1. https://en.wikipedia.org/wiki/Cambridge_Analytica#Data_scandal https://en.wikipedia.org/wiki/Cambridge_Analytica#Data_scand... 2. https://www.protocol.com/nyu-facebook-researchers-scraping https://www.protocol.com/nyu-facebook-researchers-scraping
