My money says google won't go through with this.
First off, they will lose money, and being a public company now, the investors will not like that. They've gone a long way from the "do no evil" approach and are now just another big corporation that answers to its stock holders.
Second, they tried this before, with adult domains. Soon enough, they went back and were monitizing them.
Finally, this won't stop tasting, it may stop kitting. Like the other guys said, all the taster has to know is whether the traffic and clicks are there, because if they are so will the cash.
