I use Instagram on Android because it's heavily modified and stripped to its bare essentials just for responding to friends. Prior to this I used the web app. If those two disappeared I would be done.
That said, I see your point. I wouldn't use Instagram if I couldn't do these things. If Google cracks down on user choice to a degree that even adb can't work around, then I'm out. Motorola's Graphene OS phone can't come soon enough.
