On second thought: this is the first time I've read about a cellular provider using triangulation to find out the precise location of a user. It is not something I expect to be necessary for their own business purposes; for that, it should suffice to know which cell tower a user is connected to, and the data does not need to be stored as it is ephemeral. I would worry about this precise location data (edit: or even the imprecise data) to be marketed or used for anything except maybe law enforcement, and I also wonder why it is stored at all. If it is stored because of data retention regulations, and the provider wants to market this data, even if anonymized, I would see that as a problem, because other parts of society would start to expect, and depend on, such data to be available, perpetuating this data retention.
