Android app developers may be unwittingly sharing their users' location data with advertisers

Filed under: No shit.

This is why I sell apps, and don't mess with ads.

As an end user I don't use ad supported things, and block all ads, so I can't justify writing apps that have ads in them.

If your app is worth having, it's worth charging a few $ for (or adding a subscription if the app requires ongoing content generation or constant updates).
