Google Store [googlestore.com] is now using Adwords to advertise its products. In many cases these products are just commonly advertised items, but with the Google logo added to them, such as
this headset [googlestore.com]. Adwords has many clients advertising this same headset, without the Google logo on it, and similar, competing models of headsets.
Similarly, Google uses Adwords to advertise employment with Google. However, Adwords has many clients who use Adwords to advertise their job boards and recruitment services.
I don't think this is fair.
