Public Knowledge notes that the hands off the Internet coalition, spearheaded by AT&T, has written a letter to the FCC asking them to investigate Comcast for network neutrality abuses. The group, which is staunchly against network neutrality laws, wants the commission to investigate and act quickly if the cable company's practices violate their network neutrality principles.As we've mentioned previously, the FCC policy statement (pdf) is not law, and the FCC and Comcast will simply argue Comcast's practices fall under the realm of "reasonable network management." AT&T's group knows that this will be the FCC's conclusion, so the letter serves two purposes: put on a stage-show that suggests the industry can self-regulate, while giving Comcast a little additional negative press in the process.
