“What would it mean for your business if you could target potential clients who are actively discussing their need for your services in their day-to-day conversations? No, it's not a Black Mirror episode—it's Voice Data, and CMG has the capabilities to use it to your business advantage.”
The biggest criticism for the idea of phones always listening and sending that data somewhere ia that they would also be listening to other corporations and their meetings. Even if multi-billion corporations can just waltz over the rights of normal people, other companies would be very interested in knowing this is happening.
Also I feel like they already know this stuff so they gain very fucking little in listening on us. You saw an interesting website two days ago and spent more time in it than normal. Then you meet uo with friends whom are known to have similar likes as you, why the hell would ad companies not show ads for the same page / item / event to those people. It doesn’t matter at all if you mention it or not. Companies already know what products and brands you like, if your friends search for something, obviously they get ads of products that are interesting in their circle of friends. The items / brands / whatever are being talked about because they’re interesting to the circle of people, which companies already know.
