Mark Zuckerberg says that Facebook collects data even if you dont use Facebook

Ever since the Cambridge Analytica data breach scandal made headlines, there has been some new news or statement from Facebook. Now with Mark Zuckerberg’s testimony before Congress is going on, there are new revelations every day. In the first hearing, Zuckerberg told the Congressmen that his own data was also compromised in the Cambridge Analytica Scandal.
