Let's not confuse GPS and photo satellites.
The GPS birds are transmit-mostly. They are like the North Star: you can see it, you can work out where you are. A little trickier because the GPS birds don't stand still. But cheap computing makes it a $5 job to work out your location from several observations. They do not listen much, although they must hear a time-code from somewhere, and there was a "smear" option turned off a few years ago. They certainly don't know where you are.
The spy-birds are up there looking down all the time. There are several levels. There are photos from mile-high civilian airplanes doing surveys and map-checks. In crisis, a spy-plane can buzz a part of the world from above AA-missile range. There are eyes at geo-sync orbit (23,000 miles) keeping 24/7 watch over huge corners of the world, essentially looking for rocket-launches and bomb tests. Weather photos come from these and some lower birds.
But the see-your-house photos come from low-orbit satellites. Roughly 100 miles up, 20 mile swath of ground. In polar orbit, it takes over a thousand orbits to see the whole world, each orbit over 90 minutes. Half the time the ground is dark, and some of the daytime is cloudy. A single satellite won't see you more than once or twice a year. There are multiple satellites, but not a gigantic number. If "they" are watching me, they probably don't get more than one look per week. And if they are not looking for me, the data-stream may get stored for months before anybody uses it.
I do not believe they can do face-recognition from orbit. Air turbulence defies such acuity. For stationary objects like bunkers and silos, averaging will improve the image; maybe they can read manhole cover numbers. But unless you lay dead face-up for a long time, they can't read your face.
The out-there Truth: Bermuda Triangle. People vanish. This is because earthlings are tasty, and if you catch them at sea or in flight they are pre-crated/canned and ready for transport to food-shops on Jupiter. Because of over-hunting, earthlings are now rare in the historical Bermuda Triangle, so the hunters have moved further down the coast where surveillance is thin.
