"Now if only you can find out how to block that faceboob pixel from "phoning home"..."
It's called "Disconnect for Facebook" amongst other things.
However as you have to use as the _only_ available method to explicitly block FB from snooping in your activities, it's more or less proof that FB are NOT indulging in "informed consent" when it comes to their data gathering activities.
Consent is not fungible. Someone else cannot give it to a 3rd party on my behalf.
