Does not address Apple’s specific allegation, that the EU demanded that competing AIs have direct systemwide access to all apps and data, while Apple wanted to add an intermediation layer which Siri or competitors would plug into, and which would force the same level of user visibility (a popup at the top) over any AI’s behavior.
I don’t know why the EU allowed Apple to intermediate other browser engines with BrowserEngineKit, which is unacceptable, while blocking it here where it is reasonable.
I think EU's position was that Apple can impose whatever rules and restrictions on 3rd parties as long as Siri is itself subject to ALL of those rules and restrictions. The restrictions were up to Apple to determine. What was not OK was to roll out Siri without restrictions yet impose them on other AI providers.
