Historically, from emails and the such made public through the courts, Apple has resisted making such deals.

Apple made deals around app permissions.

However the economics have changed now. It’s no longer practically free to support iOS. So some companies could make a reasonable argument that supporting iOS is too expensive when only a fraction of their customers do in app purchases from Apple hardware. So from Apple’s perspective, they now have more to lose in not making deals. While app developers have more to lose in supporting Apple.

This might just tip the scales into forcing Apple to negotiate on more than just app permissions.

Except the price only exists for large spenders in the first place.
