It's really hard to follow your train of thought. Bluetooth isn't a piece of metal in your phone. It uses the same antenna your phone needs for its other wireless connections and it's also driven by the same modem. Compared to an audio jack its impact is miniscule. The demand for Bluetooth wasn't created in 2016, it predates smartphones. There were countless wireless earphones before 2016 and they mostly weren't even made by phone companies. Apple removing the headphone jack wasn't 'false advertising', it was very well publicised.

Yes, phone companies removed the headphone jack from their phones to drive the sales of their own earphones. Yes, Google collects lots of data about you. But interpolating these to "Google wanted people to keep Bluetooth on for its spy network" is a far fetched conspiracy
