How so? I'd imagine the datacenter terminal side downlink to be much more easily tappable than fiberoptics.

There are advantages in latency and potentially availability, but even there I would imagine fiber to win in an adversarial active jamming scenario.

I suppose in any realistic scenario we should assume that the enemy may be listening to all our communication at all times. This is the assumption behind such daily things as WPA3, SSH, TLS.

Jamming is a much more serious concern.

FHSS[1] has made jamming difficult in US military communications for decades. It doesn’t make it impossible but jamming the entire spectrum is nearly impossible at scale for almost everyone. At best it would affect small areas until the US sent rf seeking missiles (HARM are designed for this) at the jammer source. Also note that modern satcom like Starlink uses AESA digital phased array antennas much like a F35’s radar. It’s so much more complex than legacy analog stuff.
