Adam Grossman:

(…) we also believe that Apple and Google should do more to prevent this sort of behavior. They should set — and aggressively enforce — clear App Store rules forbidding the sharing of location data for any purposes not directly relevant to the app’s core functionality. If an app is caught breaking this rule, it should be removed from the store. This won’t stop all abuse, but it would, at the very least, put many of these data monetization companies out of the business of tracking where you go.

I completely agree and have much respect for the DarkSky team for their declarations. Especially since Adam also posted many examples of companies, such as Reveal Mobile, contacting them and offering to pay for their data. In the meantime, AccuWeather’s response on the matter was a non-answer.
