Gruber's 'Wading Through AccuWeather's BS Response' →
'The accusation has nothing to do with “GPS coordinates”. The accusation is that their iOS app is collecting Wi-Fi router names and MAC addresses and sending them to servers that belong to Reveal Mobile, which in turn can easily be used to locate the user. Claiming this is about GPS coordinates is like if they were caught stealing debit cards and they issued a denial that they never stole anyone’s cash.'
