Robert this is not a rumor actually. It is published in the google's website in the page "Adsense for feeds" under Google's adsense products.
I think if google is planning to close the feed part alone, then they will definitely try to introduce a new strategy to earn more money than the feed part. So why should we worry about this?
If there is no change then there will be no chance for the development of new technology. We have to accept the change.
Let's expect a new type of earning method from google.
