Great point from Jeff Johnson on the arbitrary tier 1 / tier 2 differences in Apple’s proposed EU rules:

What I found striking about the search differences between Tier 1 and Tier 2 is that in creating this distinction, Apple clearly considers App Store search to be a developer feature rather than a user feature. In other words, the user’s interest in finding an app via search is disregarded, and Apple is willing to be less helpful to users to the extent that app developers pay a lesser commission to Apple.
