At what point is that abusive versus just good business. What if Google had two prices where one was for customers that used their android services (store, geo-location, etc.) and the other was for those that didn't want the geo-location service. It makes sense for Google to offer the clients getting everything a lower price as they can make it up with their geo-location service.
Is that considered abusive? If so then most companies would have to be considered abusive.

I don't see it as a sudden change since they had been fighting this war for a number of years. Sure, the FCC had come down on the side of the cable companies most of the time but the fact that the issue of network neutrality came and kept coming up year after year shows that this isn't some sort of massive change out of nowhere. It was a clear reaction to the cable companies refusal to work with the FCC as they clearly kept saying 'I'm not going to do what you want and you can't make me.' This is just the FCC stepping and saying that they can make them do what they want.
Given what the courts have said in the past I don't see a challenge to the FCC rules coming from the courts. Congress is another matter.
