Despite all of Facebook's benefits, they have also faced criticism for some of their decisions and practices. Most notable is the way that Facebook has handled user data and privacy. They have received significant backlash for multiple incidents including the Cambridge Analytica scandal, which involved the use of user data without permission. In addition, Facebook's decision to include questionable content in its 'trending topics' has drawn much scrutiny. Furthermore, many users have complained of having their personal information shared with unauthorized third parties.
