If you think you can legislate the world away from big data and data mining through legislation you are terribly naive. At most it will punish a few surface level players like FB while the massive industry continues to flourish at every single major consumer company with a modern marketing dept. Not to mention the many billion dollar companies you've never heard of who trade in this data, all the consumer financial companies, the government itself (IRS and security agencies), etc etc.

This rabbit is not going back in the hat. We need better tools which respect users, behaviour change via a new common sense, and decentralization. Not flashy legal theatrics that is out of date well before its written in law.
