Is AT&T Building the Ultimate Walled Garden?

itwbennett writes "The announcement earlier this week that AT&T joined OpenStack was greeted with much fanfare (of the 'woo hoo for open source' variety). But dig into why AT&T decided to sign up for OpenStack and things get a lot more interesting. 'AT&T is about to take on Amazon's EC2 and S2 cloud services, and OpenStack's technology is going to be the engine that drives it,' writes blogger Brian Profit. 'Leaving aside the potential problems for user privacy here — and oh, there are many to be addressed to be sure — a plan such as this would represent a stunning coup for AT&T, since they would be able to provide the one thing Apple and Google have not been able to have in their respective plans to own the entire stack: the network on which all communications must flow.'"
