The problem with VPNs is that while they can enable privacy on a deeper level than Apple can in some cases, they also potentially pose a grave threat, as seen with Facebook’s “research” VPN which got shuttered not so long ago. It’s a tough problem because there’s no way to verify what’s happening on the other end of the VPN during the app review process, and even if there were its too easy to change how the VPN operates to pass review and then flip it back afterwards.
