It is obvious that Facebook is facing one of the biggest lawsuits that it has received in some time. It is not only Mark Zuckerberg that is being sued, but all of the other members of Facebook are also affected by this as well. They are currently facing four lawsuits right now after the Cambridge Analytica scandal.
This has also prompted people to close down their Facebook accounts and start telling other people about it. The reason why they can be sued is that they sold the information of people that were supposed to be private to Cambridge Analytica. Whatever trust that people had with Facebook in the past is probably long gone now.
When it comes to suing Facebook CEO Mark Zuckerberg for privacy theft as the result of the Cambridge Analytica fiasco, the opportunity is certainly there. The reason for this is that Facebook released this private information without consulting users. All of the ads that Cambridge Analytica used were strictly on Facebook and the private information was only geared towards Facebook and not released to other companies and or websites.
Facebook allows for third party access on their site all of the time but it is done with the users consent. Facebook selling private user data to Cambridge Analytica was not done with users consent and thus opened the door for lawsuits. With the ever increasing amount of hackers and computer crimimals these days, anybody could have clicked on one of the Cambridge Analytica backed ads and started their illegal actions. Facebook broke privacy laws so yes the company could be used for breech of trust and releasing private information without users consent.
