In December, Google expanded the AdSense for Domains product to all US publishers. Today, we are hearing reports in several forums that it has now been expanded to international publishers as well.
I was very concerned to learn in December that this extremely controversial program was expanded then. But to be honest, I have not seen many complaints since the expansion. For my perspective, things did not get worse by opening up. In fact, maybe things have been getting better with Google and fighting off certain types of MFAs and arbitrageurs. Opening this program internationally does worry me, but let's see how Google handles it.
Right now, we have very little feedback on the implications of this move. The best thing is to wait and watch. Oh, trust me, as soon as I see complaints, I will bring them to you.
Update: Google has confirmed with me that Google has indeed opened up AdSense for Domains internationally.
