Sure, I mean one way to combat this is through data warfare and sabotage. If enough people behave erratically and poison the well of data it will make it harder for these companies to infer as much as they do now.

For example, click, view, watch, like at random ads and if enough people do this inference will be harder.

On the other hand, whatever brings power away from large telecoms is good for all of us, even it means integration with Google makes calling simpler and easier.

None of these companies are our friends. Not even in the 'enemy of my enemy...' sense, as these companies happily partner with eachother whenever it makes sense financially.
