Assuming 30m intervals and a 1m GSD I can know when someone is or isn't home based on whether or not a car is in their driveway. For people living in the vicinity of an airport where the GSD and intervals would presumably be much higher I could track individuals to and from their home or office from the comfort of a coffee shop.
Either of the above capabilities has ramifications for things like:
- stalking and harassment (no need to follow someone physically)
- home invasion and theft (can determine when someone is out of the house)
- targeting of dissidents (can track who showed up at a meeting)
- kidnapping and rendition (can know when someone is isolated without committing physical surveillance resources)
Those are just a few of the things I can come up with off the top of my head.
Even if you limit your tools to governments and businesses what prevents illegitimate organizations from using shell companies [2] or other means for establishing legitimate accounts to your services, and what prevents individuals within legitimate organizations from accessing the tools for personal means?

Calling this a "PR issue" grossly understates the potential damage a technology like this can cause in the wrong hands.
