The US government has received more than 9 million public comments on rolling back network neutrality regulations, a record response to this hot-button issue that both sides argue plays an essential role in who gets Internet access. The first public comment period ended July 17, and now a one-month rebuttal period is underway. Already, about another million additional comments have been submitted. Those totals were boosted by July 12's online 'Day of Action' conducted by tech companies and liberal privacy rights organizations that support the net neutrality regulations, as well as opposing comments from those in favor of overturning the rules.
