Or the weather app is selling their location data to one or a hundred data brokers every 5 minutes. Mobile monetization via third party SDKs is a big thing. Likely 100k different SDKs to choose from (a number that came from a data aggregator). Add in mobile operators, etc, and recombine the anonymous ids with the help of LiveRamp et al and it’s just a simple data problem.
