Well there's the disingenuous way in which they present the choice, defaulted to opt in with flowery language, versus the popup third party developers have presented to their users.
There's also the "app store health card" which the cynic in me would say is designed to scare people away from "competing" apps, because none of the Apple equivalents have a health card. Additionally there's no nuance - both iMessage and Twitter ask for location data - but only if you want to share your location. End result? People looking at Twitter in the App Store surmise "well, they must be tracking my location at all times!".
