Again, satellites are taking pictures and listening to conversations. Big deal if drones are flying over. What’s the difference?
Lower angle can show different and better details. Close-ups and resolution can reveal more stuff. While satellites have better cameras they are still 200 to 20,000 miles up. Not to mention cloud cover, atmospheric issues and just plain dirt/pollution.
Most (spy) satellites are owned by state actors. Obviously this is not always true, but most state actors have relatively stable geopolitical relationships or a kind of stasis. Most commercial satellites (that publish) are not high resolution, and make agreements with governments not to show (or to redact) sensitive information. What is more, the information is not real time or even recent.
Drones, on the other hand, pose the risk of having realtime information revealed. Same with you going to a base and snapping a picture. It could be sent to someone or published online in moments.
Why they wouldn’t be shooting down drones and just closing airspace, I think, is revealing.
