Don't let the fascists fool you, there are alternatives to Starlink. Eutelsat in France, Telesat in Canada and Inmarsat in the UK, just to name a few examples.
Technically, and this is purely semantics, coverage is the major downside to starlink. They are faster, though.
The coverage of satellites has an exponential factor of the distance of that satellite to earth. If you had the satellite further out then its signal could reach a wider area before being cut off by the curvature of the earth. However, as the distance increases, so does latency.
Now, I don't know, but I would assume its the latency. Starlink has a (impressively) low ping of < 100ms, while existing alternatives usually have 600ms+. Now, that's only relevant if they are using it for stuff like flying drones.
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.
