Same story for mobile service providers. Cellphone companies have known your "exact" location for the last 20 years. There is a lot less oversight or scruples in the engineering teams of providers (that I have worked at) then I have seen at Google and the likes. Nobody (but a couple of spies, smart crooks & prewarned govermental types) take any measures to hide from them, or complain about this information being available. Luckily for us, telecom companies are not that smart|agressive when it comes to finding new revenue streams. Be it based on your (phone's) location or their excellent position to offer verified identity services, since they have a payment relation with all their customers.
