What "most" of the people here want, and forgive me if I'm bringing in anyone who disagrees, is to make sure neither Comcast nor the govt gets to filter traffic or
somehow tamper with any data passing a network.
QoS has been brought into this and it is a legitimate issue but there is a difference between QoS for VoIP vs other traffic, and QoS for sites who pay up vs those
who don't. QoS wouldn't be an issue if last-mile ISPs had the bandwidth they purport to have where all users get to max out their connection if they want or need to.
On the other side there is the concern that government will create rules allowing them to censor content. A well-founded concern, given the ICE's recent takeover
of various sites and the pressures applied against several news organizations and banks.
So, again, net neutrality is needed, and all proponents are asking for is that neither the govt nor the ISPs get to mess with the bits on the wire.
