Apps can easily be redesigned with some kind of webview integration, and some apps already do have random things that bring up webview, and thia would kill them on a rooted device.
The inherent issue here is they're arguing this will help prevent fraud, but they're not looking for fraud. They're looking for an altered device and assuming fraud.
I nuked a food app recently because instead of opening so I could give them money in exchange for food they decided to police my phone for PCAPdroid by way of refusing to run beyond showing a message stating that I can't have PCAPdroid installed and closing after a 5 second timeout.
Fuck you, Papa Murphy's. What's your app doing that you're afraid I'll be able to see? You're blacklisted for life now.
I totally agree but my wife does have the McDonald's app which gives decent discounts on food. I get to live the best of both worlds by not having to download the app while still benefiting from the discounts.
As a Papa Murphys lover, I can't for the life of me understand why you'd ever need to install their app. You can order from the website just as easily.
I'll give them a pass as I assume they got some bottom of the barrel developer to cheaply create their app and it doesn't get anywhere near the level of attention that something like YouTube's app would.
