How does tracking users by IP address optimize for anything? Apple has shown repeatedly that they believe privacy is very important (Tim Cook has even gone on record as saying he believes privacy is a fundamental right), and they exert a fair amount of effort in trying to preserve that privacy (e.g. all of the data they refuse to collect, and all of the anonymizing they do on the data they do collect, which still requires the user to opt-in before that anonymized data is sent to Apple). The only way in which your argument makes sense is if you think Apple doesn't actually care about privacy, but only cares about the appearance of caring about privacy, and therefore would anonymize data it collects while still leaving loopholes for it to try and recover some of that data anyway. But that contradicts all of the evidence.
