For war it is. Drones and other unmanned aircraft are the future of warfare. That's the whole reason why every country now heavily invests in low orbit sats.
It's not about consumers. Also not for spacex. Defence contracts are zillion times more worth. Once you are in you reach the end level as a business.
Russia has attempted to jam Starlink satellites but with very limited success. The problem for Russia is that the constellation is enormous and uses highly directional phased-array radios which are naturally resistant to jamming. They can temporarily jam a few birds over a limited area but don't have the resources to effect sustained denial. We might eventually see them escalate to kinetic strikes on the satellites.
You are right about drones, but Starlink etc is still used a lot by forward deployments of troops. Afaik it has revolutionised the ability to contact these deployments. But I'm not an army guy
