When authoritarian states block websites, most people use a virtual private network to circumvent the restrictions. But that’s getting harder.

Meanwhile, Apple has bowed to new Chinese restrictions, which demand that developers offering VPNs must obtain a government license, and removed such software from its App Store in China.
