How does this provide any more data for fingerprinting than just checking the model of the phone?

My previous phone got an OS patch every few months. You would get most of this by reading the phone model and Android version, but there's probably a smidge more information in the library versions

Harder to spoof, less likely to be faked, plus additional meta information.

For starters, I'm not convinced it would be harder to spoof that than the library information (which also seems pretty easy to spoof if not easier).

But even if that were the case, why would they spend this level of engineering effort just to be able to fingerprint people in that extremely rare case of having a spoofed phone model? Do you think that kind of customer would even be receptive to targeted ads in the first place? It just doesn't make sense to me.

Tracking value increases with rarity. Data is packaged and sold, not simply stored and empty cells can go for crazy money if the target is hot enough.

How much would you pay for Elons verified personal number?
