Howdy. I'm an engineer on both Facebook Container and Relay.

We fixed the original bug in Facebook Container that was showing the prompt on every website - now it only shows the prompt on websites where Facebook trackers are detected.

Facebook Container is something that inspired and influenced the development of Relay in the first place. Facebook Container users reported that they used websites and still saw ads from those websites in their Facebook feed, even though they were using Facebook Container. Because Facebook lets anyone create custom audiences for re-targeting, we need to give users a way to protect themselves from "back end" data sharing & tracking.
