If they were flying to a pre-programmed destination then the up and down link wouldn't be required. This would make RF jamming on up and downlinks pointless. Jamming GPS frequencies would have so many implications for all the other users that I would doubt it would be considered.
As for anti-aircraft use of drones, only two would be needed to take out the majority of airliners. Jamming of up and downlink frequencies would be worth doing in this case, as the video would be necessary to home in on the target.
The intentional nuisance value of drones should not be underestimated. A number of them flying a GPS racetrack course could close an airport for an hour or so, whilst attempts to down them would be likely to create a FOD hazard.
