To add on... No ability to firewall their iOS devices leaves use of the network vulnerable. Siri and other unkillable daemons always running. My favorite is when the cpu fan "stopped working" on an old A1278 after an update. Turns out that was just a change in the fan profile so the machine would cook first before the fan would wheeze out a puff of effort.
Not viable for a non-superpower to create and deploy a successful hostile drone, and imagination is cheaper than reality anyway.
Aside from the hostile drone command and launch being found and destroyed, the drone itself would either be shot down by a missile or disabled by a direct energy weapon.
If the drone were to fault on it's own and was designed to float, it will be expensive to retreive it. Cheaper at scale to launch the sensors into orbit or deploy bouys.
Nothing has been thrown away, evident by billions of dollars in the continued success of many flagship products that leave the competition in the dust.
