I can't scrobble my music to last.fm on iOS without some janky workaround. The "almost same level of control" part of what you said relies on an assumption that only the set of use cases explicitly determined by Apple as ones that "matter" are worth supporting. That it's more important to prevent the user from explicitly allowing a scrobbling app permission to read the music player app's now playing notification than for the device to be able to perform this simple function.

This point of difference doesnt have any meaningful impact on collection of my data. It just stops the device from being able to do the function I want. So that what, I can sleep easier knowing that Apple designed a slick interface to point out data vectors which were already implied to be collected? It used to feel like a smartphone with training wheels, now they've just locked up the handlebars so that it's easier to go straight.
