it's unreasonable to expect Google to change how the network operates just because you aren't happy being a guinea pig

Rubbish, any company shuold give you fair warning of any changes they make to their service to you before launching it. Then you can decide to continue showing their ads or not. In a production enviroment you simply should not expect to be treated as a guinea pig.
