If China owns the internet; and, I suspect with substance that they do, in collab with the amount of U.S. land it owns (think Cali), it could happen, and without/limited/controlled WI-FI there would be very little the ordinary man could do about it.
I read today that a former FCC chair says internet needs regulations.
I do believe that Black Mirror (?) segment was just getting people ready for what may be coming down the pike.
Let's face it, the fewer people online, the more power the powerful have.
Maybe, for a brief time; but, BLM, Yellow Jackets, and the hundreds of other 'revolts' don't last...
