Nobody is interested in giving FB a warning. If you ask me, prison time for execs in addition to at least $10B yearly fine makes sense. They intentionally did things that harmed millions of people, the idea is not to just make them think twice before they do something like that again,but to make the message loud and clear: "that move is a fatal move". Not just for FB but for all others who make money out of user surveillance (snapchat,linkedin,google,etc...). We don't want to give them a risk they can calculate and evaluate,we want to give them a risk as clear as death, a risk no company will even bring up in any meeting.
