Also the level of detail people are fretting about in the comments in this thread aren't going to happen with a smallish company's satellites these days. Your maximum resolving power is a function of the wavelength you're viewing and your camera's physical size. That's a hard, absolute, basic-laws-of-physics limit. It can't be coded, engineered or throw-more-moneyed around.

If a hypothetical SpyOnYouCorp wants to know what book you're reading or whatever other scifi level of detail, they've got two and only two options. One is they can get closer; that isn't possible in the case of these satellites, since if they get any lower they'll reenter. The other option would be to make enormous, swallow-Hubble-whole imaging satellites, and putting a fleet of those in orbit will present its own set of problems.
