Techno-Feudalism
I'll say it, yet again. It's just feudalism. "Techno-Feudalism" has nothing different enough to it to differentiate it as even a sub-type of feudalism. It's just the same thing all over again, using technological advances to improve the ability to monitor and impose control over the populace. Historical feudalists also leveraged technology to cement their rule (plate armor, cavalry, crossbows, cannon, mills, control of literacy, etc).
