Starlink has enough uplink to be able to handle live video streams and a latency low enough to do this with simple tools.

I’m not sure if that still happens, but I’ve seen some pictures of Ukrainian command bunkers literally getting drone feeds using discord screen share.

It’s faster, cheaper, and on the tech side more reliable (definitely not politically reliable though).

My guess is better coverage and latency with its sheer number of satellites.

They use low earth orbit, which require them to use more satellites, but lowered latency.
