There's plenty of non technical teenagers in Pakistan with VPN clients on their phone or laptop who seem perfectly capable of using a VPN to watch Youtube or access Twitter and other social media, during the periods of time that the government orders things to be blocked.
Even my third-grader was able to figure out that she needed a VPN when I blocked Roblox's IP space (128.116.0.0/17) on my home router.
Other than, as reports said, soldiers snipping cables in datacenters, regimes will have a difficult time completely blocking whatever they don't like. Even China can't do it.
Thanks,
