I'm not sure these trackers are the worst possible as they could be used for things like crash analytics. However, unrelated to this specific case, I believe that mobile apps could be the one place that adblocking cannot be guaranteed to work. When things get byte-compiled, you can no longer programmatically inspect the interface and remove malicious ads like with the browser's runtime. Imagine a future where a critical feature you have to use like banking is only available through a mobile app, and this is enforced through something like a certificate check. Then they run ads over it. DNS based blocking is not infallible either. Even today it does not work with the YouTube app, because their ads are served on the same domain as the content, so blocking one means blocking both. The only solution people have come up with is reverse engineering the official app's source code and releasing a modified version, a process that consumes far more time and effort than using something like uBlock. And this was only prioritized and accomplished because YouTube has become that important of a platform to enough people. If there's a future where our lives depend on compiled apps, will enough people go through the same effort to sanitize all of them?
