The reason that FPV drones are so easily disrupted is that they are too light to carry anything more than a radio and fly low.
Disrupting the signal for a normal-sized aircraft is much harder. If you're flying at 10s of thousands of feet and have a line of sight to multiple satellites it's going to take some serious weaponry to disrupt that.
Latest FPV drones in Ukraine became much more resistant to electronic countermeasures. Plus other drones are used as retranslators.
True. But the next rung up the escalation ladder is of course disrupting the satellites.
