Maybe it is, maybe it isn't, but that's not actually the issue in question. The comments to the FCC board were made using (publicly available) real name and address pairs.

Someone submitted a comment using my legal name and current address. Whether that person should have been able to comment pseudonymously or not is beside the point. What they actually did is make a public statement in my name, which may or may not reflect my actual views, and which definitely impedes my ability to express those actual views if and when I desire to.
