You assume it would be used for mass spying. Not at all. When you have something that good, you use it for specific targeting. You get a guy with a work laptop at home, you infect him, then you use the machine to get one closer to your objective. Slowly. With time between the events. Without being a beacon in the network. Or you just use it to spy on a guy you suspect. Or to get access to secrets of somebody you wanna black mail.
