> This is absolutely not the case. Google’s biggest ad clients achieve pretty incredible ROI (called ROAS) on each dollar they spend. It's their job to figure out how to best advertise, not mine to hand it to them on a silver platter at my own expense. This is my data, information about me, which they are stealing without my knowledge and profiting from. If someone asked me if they could snoop around in my personal affairs for money, the price would be a hell of a lot higher than the big fat zero I get in return here. Whatever Google or Facebooks' advertising ROI is, does not make it ethical or interesting to me. Credit cards get the benefit of knowing where I shop, but at least I know when and how they are getting that information. Likewise, cellular service. It's a price we pay for ubiquitous access to information. But I would cut them bot off as well if there were some way I could. It's parasitic and it's zero benefit to me.
