Yep. It's not surprising people fail to apply the same standards for privacy to things they are dependent on but it is sad. And it's not just smartphones but any cell phone. They're all tracking ankle bracelets.
But more back on topic, buying everything from one store, as amazon's 'Prime' and business practices are focused on, represents a fairly large privacy risk and centralized liability in and of itself. Better to just buy from wherever has the best price/etc.
