Richard Bennett writes: Activists on both the far left and the far right were upset about the FCC's Open Internet order issued this week. The left found too many loopholes, and the right rejected the FCC's claimed authority to regulate the Internet: It's another classic net neutrality food fight. The order itself casts doubt on the ability of the FCC to evaluate complaints and reach the right conclusions about which specific ISP practices are kosher. It contains significant errors of interpretation and technical analysis, but does suggest that a technical advisory group will be created to help FCC staff figure out what's going on. The success of the Open Internet regime has less to do with the rules than with the process for judging actual cases.
