We don't perceive this news to be much offensive for Apple fans to include a CAUTION or disclaimer at  start but yet, it is perceived to be some kind of offense( funny though). Apple's famous personal assistant SIRI which is known for its sarcastic tones and peculiar traits has started to show some kind of freakish and volley behaviors towards “Google Glass”. Exerts perceive this to be a categorical and onslaught injection of mugging to gain competitive edge, which has been a factor of immense importance both for Apple and Mountain View’s giant, Google.  It's important to note that all these comments are from latest iOS 6,though beta of iOS 7 offers even more Glass-related comebacks. Look at these attacks from SIRI.
