The thing they were fined for was
>[Google] has required manufacturers to pre-install the Google Search app and browser app (Chrome), as a condition for licensing Google's app store (the Play Store);
How is the Play Store related to the Google Seach app or to Chrome? One is an app store, one is a seach bar and one is a browser. They have nothing in common and don't interact in any meaningful way (except perhaps the interaction between the Google Seach app and Chrome, but that relation isn't part of the ruling).
This is clearly Google using the dominance of the Play store to push other, completely unrelated apps.
>zero customers want a vendor to do anything different
The first thing I do with a new phone is to try to get rid of that google search bar on the home screen (I open a browser to seach the web ...), I don't use mobile chrome, and I prefer rooted CyanogenMod / LineageOS over stock Android. So I am clearly impacted by all three offenses Google was fined for. I suspect I am not the only one.
