A car insurance company will offer discounts based on scanning all the text someone has posted on Facebook.

Participation in this is "voluntary", but if it typically offers significant discounts, non-rich people will say they "have no choice" about posting on Facebook. This sort of system trashes people's rights in practice even though in theory they still have the rights. We therefore should prohibit it.

"Wait until insurers can see the contents of your fridge."

Don't get a refrigerator which keeps track of its contents, dummy!
