Apple is using the conservative approach, which is to misrepresent their starting position by moving the goal posts to an extreme. Then they bargain towards the "middle". It creates the illusion of bargaining.

So Apple is throwing a huge tantrum and withholding features from the EU to act like this is a much bigger deal than it is. This gives Apple a lot more bargaining room after the EU bitch slapped them.

Apple likely already has an API they could enable and be done with this. They won't do that. Apple needs exclusivity with new feature releases because they don't do things all that well anymore(Siri, maps, etc, nobody uses those because there are better alts available on ios).

But yeah Apple is just starting way to the extreme so they have more room to bargain. Hopefully the EU sees through this, again, and doesn't budge.
