And when it comes to privacy, consumer advocate types and privacy wonks (I include myself in this group) want the heater to be on, and technology companies and advertising companies and all of their hangers-on want the heater to be off.
One group has a lot more money, power, and influence than the other.
I think the problem here is more that _some_ people want the heater to be on and _other_ people want the heater to be off.
