This is what comes of privatizing "The Tubes." Via Slashdot.com, AT&T has some fine print in their policy that claims that it can suspend or terminate your online service, effectively cutting you off from the public Internet for "conduct" that "tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries."
Hence, AT&T subscribers, you are not free to express any criticism or dissatisfaction that AT&T interprets as damaging to their name or reputation unless you want to risk being disconnected.
Last week Verizon pulled an about-face for refusing service to a pro-choice group based on no other reason than their political views. AT&T keeps their manipulation of attitudes on the down low in the fine print, so as not to draw attention to those occasions or draw fire at their company when they drop someone's service because they didn't appreciate that person's opposing point of view. They also would like to avoid adding more fuel to the Net Neutrality cause.
This is the kind of repression that comes with corporate privatization absent citizen-protective regulations. Make sure you read your fine print and oppose all AT&T's attempts to annex the web.
