Now please answer my question: why would they want to?
They want to control peoples access to on-ramps, not shut them down.
Even that's a stretch.
What they want control of most of all is KYC/AML access to all online services and social media because once that ID is keyed to your salary/bank/medical, they have control over your behavior.
Suspsending ISP's is retarded. It solves nothing. Online engagement > internet exile.
