Unless the satellite is meant to collide with another object, it's never going to be considered ammunition. It is a strategic platform for communication or intelligence gathering or maybe both. So calling a satellite ammunition is just belaboring the point for internet points or something.

No, you're still missing an important point. This isn't just semantics. Some types of satellites will be considered ammunition in the same way that some (expensive) aerial recon drones and decoys are already considered ammunition today. Not all rounds of ammunition are intended to physically strike a target.
