With the increasing development of capable drones, I keep wondering how long it's going to be before we start seeing people who have given up on law and regulation resorting to drone-enacted vigilantism.
Drone warfare relies on large numbers of drones overwhelming enemy electronic warfare countermeasures, in urban or open landscapes that haven't been specifically designed against it. A billionaire in a western country against a rag-tag group of guerrillas making drones from commodity radios is just about the least favorable conditions for it that could exist. You may catch a couple of them on accident up front, but they're very well-suited to adapt to it.
I'm not a drone hobbyist, but it doesn't seem like it would be that difficult for motivated residents to do significant damage to an unwanted data center via drones.
