How is Google abusing the data collected in your context? You gave your consent when you setup your android device, right? You want Google voice or Siri? They surely benefit from all your data.
In the same way you cannot just sign a contract that is against the law, a company shouldn't be allowed to do whatever they want with your data, just because they made you click on an "Accept" button.
So basically consent to use your data is a lifetime contract. I think you should be able to delete(I don't mean disable) your data from the platform when you sever ties with a platform.
