… ok but being a terrorist ironically just as a concept sounds kinda cringe.

Tho theoretically one could prob incorporate, purely for purposes of irony, billionaires own tools into the drones to customise them, keep things fun (after all, the point of terrorism is to inflict terror damage on the opponent so keeping class solidity would make sense).
Like some drones could be controlled by their own AIs, some drones would be coal powered instead of battery, some such diy drones could use a military drone as their main payload, etc.
