As I mentioned in my other comment, it might be the case in order to monetize users personal information Facebook enabled personal data feeds, without realizing it's use case. "Cambridge Analytica" is just one of the companies whose details are out due to political implications. I am still not sure if Facebook did anything to move away from monetizing user's personal information. Indeed after "Cambridge Analytica" added "WhatsApp" and "Instagram" as additional personal information collection data conduit. Still today the only business Facebook earns all it's revenue is providing user's personal data feeds to millions of companies, may be with some additional procedure to fulfill the law on paper not in spirit. So they might just be doing enough, so that they are not prosecuted. Its not a pro-active effort to move away from economy of selling user's personal information for profit.
