Don't they already have 3rd party applications that people can use to filter content? Stuff like Net Nanny already provide children-friendly sites and age-specific ratings.
If they ever develop this silly rating system, where can I get a list of the filtered sites? These are the sites I want to visit.
Net Nanny/etc. have the same problem as this proposal when it comes to the list being subject to someone-else's 'what you can not see' agenda. As to getting NN's or the proposal's list of what is being blocked (or even the blocking criteria) that is secret (to prevent the censor from having to identify their bias/agenda).
The problem I have is not with the filtering methodology, but the proposal to force ISP's to offer this to customers. Like I said, these already exists for those people interested in some type of internet morality shield, I don't want the ISP to be anything more than a provider for a dumb pipe.
