Rather than going through 1000s of app companies, why not go directly to the 100s of third party analytic companies? From my research most all apps use some SDK which tracks users. Many apps use 3 or 4 for various marketing / product / business use cases. I've been tracking this on https://appgoblin.info/companies https://appgoblin.info/companies if anyone wants to check. Try looking at the "no analytics" found groups, which are just apps I haven't found evidence of 3rd party trackers, almost certainly they do use them. I would like to see world where Angry Birds data at least stays on Angry Birds servers and have been working on building a part of that with OpenAttribution (https://openattribution.dev https://openattribution.dev) to let app/game companies build their marketing pipeline with at least one less tracker in the app. I think as compute is getting cheaper a lot of this should/can be self-hosted by at least larger companies so they have full control of their BI tools and the data underlying it.
