There is a guide and it's pretty clear: https://support.google.com/googleplay/android-developer/answ...

"For example, if your app displays the brand, icon, or title from another app [...] your apps can be suspended and your developer account terminated."

I was trying to feel some kind of sympathy for the guy and though that maybe the terms and conditions may have been full of jargon and hard for someone without a legal background to understand. That's about as clear as can be.
