Google was openly copying an API for compatibility. Similar to how a toaster company may make their toaster support bread exactly the same size as a competitor does. The toaster company would advertise the compatibility, not hide it. In this case this company is being accused or taking the API design as well as the supporting documentation. Not for compatibility reasons but to represent the design as their own.
