Cable and Phone companies around the country are trying to hijack public wifi frequencies for their own profit.
As part of net neutrality rules, no public wifi should be closed to the public. There should be no passwords and no "terms and conditions" to utilize what is part of public airwaves.
Open standards and open networks are necessary if we are to have innovation, and to have a large swath of public wifi space blocked off goes against net neutrality philosophy. It also stifles the internet in general.
