A new Free and Open-Source project called "Exodus" scans Android apps and already has found many advertising trackers:

"Researchers at Yale Privacy Lab and French nonprofit Exodus Privacy have documented the proliferation of tracking software on smartphones, finding that weather, flashlight, rideshare, and dating apps, among others, are infested with dozens of different types of trackers collecting vast amounts of information to better target advertising.

Exodus security researchers identified 44 trackers in more than 300 apps for Google's Android smartphone operating system. The apps, collectively, have been downloaded billions of times. Yale Privacy Lab, within the university's law school, is working to replicate the Exodus findings and has already released reports on 25 of the trackers.

Yale Privacy Lab researchers have only been able to analyze Android apps, but believe many of the trackers also exist on iOS, since companies often distribute for both platforms. To find trackers, the Exodus researchers built a custom auditing platform for Android apps, which searched through the apps for digital "signatures" distilled from known trackers. A signature might be a tell-tale set of keywords or string of bytes found in an app file, or a mathematically-derived "hash" summary of the file itself.

The findings underscore the pervasiveness of tracking despite a permissions system on Android that supposedly puts users in control of their own data. They also highlight how a large and varied set of firms are working to enable tracking."

The statement by Yale Privacy Lab summarizes the situation, and the story has seen coverage by Cory Doctorow and Le Monde. Private search engine Qwant has removed trackers in its app and Protonmail is under fire.

    We need to make it more ad hoc and P2P.

    How will that solve anything? A tracker built into an android app is already just as likely to phone home to a static IP as it is to a DNS name.
    And the home address of the mothership is as likely to be the same address that services the app's primary purpose (such as a weather site).
    So the app hangs a token on the weather data request, and along with your current position, the token encodes phone number, device id, name, and every thing else the app can get its hands on.

    How does changing how the internet works fix that? It encourages that in spades.

    Well, that's what the firewall and a good sniffer is supposed to fix. Ad hoc and P2P will still help to mitigate censorship and access issues. Private connections can still be established. Nobody will be able to shut down your VPN, because we would have various alternatives to the local ISP (island hop to somebody else's), or at least provide enough separation to make tracking impractical.

      None of that stuff is the issue under discussion. You want to design a workable alternative to tcp/ip be my guest. Post back in 20 years with your first working beta.

        You want to block tracking? You have to start somewhere. Or maybe you prefer to cling to the prize you have inside the monkey trap? Be my guest... I was under the impression you wanted to make things better..

      You're right that inappropriate centralization is a big part of the overall problem, but in context here it has little affect. If you download and run binaries you have no security, the network topology really doesn't matter.
