That's a very D&D Rulebook type interpretation :). Not that rulings should be ambiguous, but usually some common sense can be applied (and is expected to be reasonably applied).

The Facebook like button is a web tracker, disguised as a social engagement button. If not its primary -, then its secondary function is to (indiscriminately) track users and non-users outside of its walled garden, like some reversed Trojan Horse.

Hotlinking an image is just that: hotlinking an image. Facebook relies on us and lawmakers to say: "We just can't ban third party content!", while we perfectly could leave innocent third party content alone, and focus our sights on the spy button. It isn't reasonable, nor common sense to conflate the two: even if similar in syntax, the context is vastly different.
