One need only look back at the previous threads on the App Store to find people arguing that Apple should be legally forced to open their platform up to competitors, which would pretty much gut these kinds of privacy-protecting moves. Facebook will immediately move exclusively to a separate app store that doesn't ask developers to justify user-relevant reasons for the permissions it requests, and immediately start demanding full permissions or else you don't get to use the app.
So essentially, people here tend to agree in principle with Apple protecting user privacy and think Facebook is overbearing and infringing on user privacy, but think Apple should be legally stripped of any tools to actually protect users' privacy, because muh sideloading is more important than people's privacy.
