It isn't unreasonable to be afraid of something becoming easy to the point of negligible, correlation of personal data across multiple databases as a result of mass data collection comes to mind.

What worries me more is what kind of corporate espionage these satellite images will be put to use for. They've been able to see the car(s) in a driveway for awhile now. But imagine: now they can pay to see what the most popular cars are in a geographical region; they can look at your deck and determine furniture brands; they can see you sunbathing; they can see what you play with, etc. No longer is it just "buying habits" but they can, en masse, buy the rights to psychoanalyze your lifestyle base on what they see from the outside of your house.

I'm pretty certain that a company paying a team of photographers to stalk the average citizen to psychoanalyze their world would be creepy, if not illegal. But this is exactly what they will be doing—and we'll have no ability to "outrun" their team of photographers. Technically, we won't even know when they're overhead.

And that does bother me.

Write an app to calculate orbital elements and pop up an alert: "Imaging object arriving over horizon, take action"

Other countries have done this for years, and cover their equipment with camo cover when opposing country assets are overhead. This is why the Air Force/Boeing X-37B is such a big deal; its an asset that can shift orbits to counterattack known orbit information.
