Wouldn't it more like having a Nike stand in a store called Google's Play App Store, with a small sign noting "this is not an official Nike stand"? (the developers name and notice).
I understand that Nike wouldn't want the unauthorized usage, but an app is a product, not a store.
Yeah, it would be more like a stand, with a huge Nike logo, and the small sign :) ( "this is not an official Nike stand").
What the developer did is hardly unique, my GF was looking for a Prezi app yesterday, and she almost installed an unofficial app, which looked really official (like the original author's, it says "This is unofficial app."):
