Why all the uproar?

I do understand why some people are closing their accounts now, but haven't many posted their personal information on Facebook themselves. Besides, personal information is available many other places. Such as your friendly neighborhood bank.  See below, "Reasons we can share your personal information." Some you can limit, some you can not.
   So, Cambridge Analytica, you know you're not the only one, though maybe the biggest and greediest.
