Craigslist blocked by Cox

It looks like Cox Communications, the third-largest cable provider in the nation, is blocking access to Craigslist.com. They're doing it through "security" software they install on a customer's computer when the service is installed. I've never been a big fan of bundled software from a service provider or hardware manufacturer. I used Cox as an ISP in the past and quickly uninstalled the software they provided, because it slowed the system down. I'm a computer geek so it was easy for me to determine the cause of the problem and eliminate it. A less savvy user might have a harder time. Why would Cox blockCraigslist? If Cox had responded in a timely manner I would be willing to believe that it was a simple mistake. Since they've been blocking it since late February I'm more inclined to believe that they are trying to limit competition to their own classified ads. Would you be okay with 7-11 paying to have the roads to thier competitors narrowed or blocked? Then why would you be okay with the same scenerio on the Internet? Where would our country be today if Thomas Jefferson had faced a similar situation? It sounds like an extreme comparrison, but it's not. The ability to stop people from accessing competative services and ideas should be severly limited. Here's the story: http://www.alternet.org/blogs/themix/37283/
