Well there is a response from AT&T:

We understand that fakesteve.net is primarily a satirical forum, but there is nothing amusing about advocating that customers attempt to deliberately degrade service on a network that provides critical communications services for more than 80 million customers. We know that the vast majority of customers will see this action for what it is: an irresponsible and pointless scheme to draw attention to a blog.
