Only meaningful if you are on a desktop machine with root privilege (which most people here do have on their personal machines) You really need a solution that works on every platform for everyone, which isn't easy. Even for VPN like apps, well, they aren't allowed on China's Apple app store. Fortunately you can switch to a different store, download the app and switch back, and Android users can just sideload an apk as usual. But that's enough to show how complex this is. (Another reason I absolutely hate Apple's walled garden.)
