Apple's Tim Cook says removal of VPN apps from Chinese App Store was unavoidable
We would obviously rather not remove the apps, but like we do in other countries we follow the law wherever we do business. And we strongly believe that participating in markets and bringing benefits to customers is in the best interest of the folks there and in other countries as well. So we believe in engaging with governments even when we disagree.
Furthermore, Tim Cook confirmed that there are hundreds of VPN apps still available in China, which are developed by people outside the country and can be downloaded via local App Store.
Apple's CEO said he's hoping the new restrictions imposed by the Chinese government will loosen up in the future since “innovation really requires freedom to collaborate and communicate.”
