The creators of several Virtual Private Networks (VPNs) have criticised Apple’s decision to remove their products from its App Store in China.
The BBC understands that more than 60 VPNs were pulled over the weekend.
Apple said it was legally required to remove them because they did not comply with new regulations.
It refused to confirm the exact number of apps withdrawn, but did not deny the figure. It added that dozens of legal VPN apps were still available.
One provider of the technology has said it will file an appeal with Apple.
