As someone that knows the person that originally tipped Apple off about the tracking... this is such a misinformed editorialization of what actually happened where I don't even know where to start.
IMO, I wouldn’t be surprised if this happened this way cause Apple had decided to use FB as the fall for a PR media blitz. (In particular, Apple made the decision to “enforce on FB” basically the day after their “someone else can turn on your camera with FaceTime without you knowing” bug.)
Enforcement from Apple on FB basically came the day after they were hit with an embarrassing “Hackers can turn on your camera without you knowing it FaceTime” bug. This part is hearsay, but, IIRC, Apple only started enforcing on the dozens of other companies that were doing the same thing once legal action was threatened for uneven enforcement. (Meanwhile, the kid that I chatted with that reported things to Apple in the first place... definitely reported more than just FB.)
