You're spot on, and that's something I think about daily. Satellite-based incumbents have an average revisit rate (assuming good weather) of roughly 2x/day, so hundreds or thousands of passes/day poses serious privacy and operational risk. We rely on guidance from EthicalGEO and other consumer privacy orgs when drafting standards, but the path to the type of hyper-revisit we're envisioning will need to be tread very cautiously.

How might this work? Could you give example of privacy heuristics you are considering?

Also curious. For example, if I run a shop and I normally have N cars parked out front, but anyone can see with 5 minute accuracy that I always have at least N-2 cars, they could easily figure out when nobody's watching the shop (or house).

Edit: also, nobody can ever sunbathe in peace again.
