The move was first noted by ExpressVPN, a provider based outside of China, which said in a blog post “all major VPN apps” including its own had been purged from Apple’s China-based store. The company shared a note from Apple (below) explaining that its app was removed because “it includes content that is illegal in China.”
The app continues to be available for users across the world outside of China, the company said. However, the process to create an App Store account in a different country is unknown to many users, so it is unlikely to fill the void of the missing Chinese app.
The App Store purge is hugely impactful because VPNs represent the only way that a China-based individual can bypass state censorship controls to access the internet without restrictions. The Chinese government effectively illegalized VPNs when new rules issued in January required them to receive government approval in order to operate. That appears to be why Apple was forced to remove ExpressVPN and others like it.
