IMO, the real underlying issue is the fact that Google has this sort of personalized info in their possession. Remember when the corporate line was that your personal data and search history was all anonymized? Clearly not true.
IP addresses are not people
I think it’s more accurate to say “IP addresses are not always people” but they frequently are identifiers and enough to be useful in these cases. So it’s a bit of an odd statement to make regarding a case where the ip address literally uniquely identified someone.
It’s like saying “fingerprints aren’t people” in a case about fingerprints linking to an individual.
