The corollary of being privacy conscious is NOT being stupid. Folks may be privacy conscious and all power to them to navigate the web/mobile world by making respective choices. However, A LOT of folks are perfectly fine trading off their privacy with convenience and value-add that comes with sharing data with companies (that use the said data to provide better and customized experiences to them). Categorizing people who make these trade offs as less smart is missing the point - and probably cynical since you can't accept them.
One would argue that it’s only because they’ve nothing to lose at the time. I imagine sometimes all the smart motivated people who would never ever run for office or be a public figure of any sort because they’re afraid of their search or post history of their teens or 20s cropping up. I’ll bet it’s actually quite a massive amount. I’m certainly in that boat.
