Nobody
wants to use a maps app that feel like it's from 2004. There's a reason people put up with giving their data away -- because data drives machine intelligence, which makes your maps app smoother, more responsive, more useful, and overall a much better experience.
I, too, don't want to give my data away. But when I'm in my car, the most important thing is that I get to my destination safely and on time. That acute need vastly outweighs my own philosophy on who I think should have my data.
I'm just being honest with myself. I can't deny that I make heavy use of products that make heavy use of my personal data. People in this community seem to think of personal data collection as a form of parasitism, but in reality, it is far closer to mutualism.
