People who are turning on Lockdown Mode in order to do a thing that Lockdown Mode doesn’t do likely doesn’t understand what it is they WANT to do. They should probably read up on what Lockdown Mode is created for before saying that “It won’t unlock my car” or “It doesn’t keep me dry on rainy days” or “It doesn’t block 100% of all network traffic from reaching my phone”.
I guess the media could say, “Here’s a list of things that Lockdown Mode on the iPhone does NOT do.” That’d be helpful. But, even after the media says “Lockdown Mode is NOT a VPN” there will still be folks outraged saying, “Yeah, but what the media isn’t telling you is… IT’S NOT A VPN!!”
Apple has acknowledged that it is a known bug that VPN data leaks and doesn’t necessarily disconnect from the connection after activating a VPM. It’s kind of the number one thing someone using Lockdown Mode would use.
