I disagree. Consider the average internet user and how much they willingly give up about themselves online. Most of them use social media and have everyone they’ve ever met added on it, they post directly about what they’re doing and often who they’re doing it with, and they lend their engagement at things they like. They use Google for a search engine and don’t block ads.

So really, for the probably 80-90%+ of the population that captures, the massive surveillance network in place just at that level is perfectly sufficient to gleam anything they might want to know. Even if someone does protect their privacy, people they’re connected with still influence their profile through their lack of concern for privacy.

So really, with all that in place, what’s the incentive to have a top secret voice surveillance system built on top of all that? It would destroy the market for any phone doing it if it was ever proven. Why take that risk when you can get everything you want from all those other sources instead?
