Yes, ads SDK across different apps can provide detailed aggregated information. Also apps promote each other, the "channel distribution" is huge business and relies on apps acknowledge each other.

I highly doubt many of the Tiktok reverse-engineering result may turn out to be some thirdparty ads or anti-fraud SDKs which Chinese companies use often.

Yes, the ads SDKs are another thing that are ripe for "disruption". And by disruption, I mean the DPAs fining and every app developer that uses any of them until the SDKs stop doing that.
