This has not yet happened even in the most authoritarian jurisdictions, with the possible exception of North Korea. The Internet is built with open protocols so any restrictions will have to be implemented on the network edge. There is no vendor locking for on-prem routers in multiple countries. As long as all purpose computers are not illegal you can still use strong encryption and anonymizing services on your end devices on your own network. So any mandatory surveillance and tracking will have no power there.
