I definitely take issue with it's avoidance of the core issues though: That the services they provide aren't optional on the iPhone. They make it sound like connecting Spotify to users, and allowing them to use their in-app purchase mechanism is a service they offer that they should be paid for. But the reality is, that Spotify has no choice but to use that service, which is the definition of a monopoly.
In that, I feel they didn't meaningful counter Spotify's primary anticompetition claim, and I look forward to seeing what the EU makes of it.
