Google Earth was funded by the CIA, before Google “acquired” it.
It was originally called the Keyhole Project-—as in, peeping through your keyhole. Think about that.

Side note, my county appraisal district uses Google Earth for duties supposedly related to property valuations. One of the employees there let it slip that various contraband activities on private property have occasionally been detected inadvertently, and referred to the appropriate authorities.
The guy that helped develop Google Earth is the guy that created the Pokemon Go app. Which was also funded in part by the U.S. government spy folks. AND - in the fine print for the Pokemon users’ contract - all data gathered (photos, location, etc.) become the property of Pokemon Go, and they can do what they want with it.
