the ISR payload tends to be massively less as well, with a balloon compared to a satellite, since balloon payloads need to be really small. they are basically an obsolete technology since the development of reconnaissance satellites, UAVs, etc, so I really doubt this is collecting much valuable intelligence. also shooting down satellites is definitely a sketchy area (see https://en.wikipedia.org/wiki/Anti-satellite_weapon) because of in-space collisions etc.
