Of course its unconstitutional. Any private company could do this. The government can not. I expect if a democrat gets in office the FCC is going to loose its head really quick.

said by BF69 How is it unconstituional? Only the FREE access is censored. How is that any different than say PBS not having any smut on it?
[/BQUOTE :

PBS is not run by the government.

Censorship is a slippery slope, however. If this is a US Gvmt project, IMO they should not censor content but instead provide free tools to end users so that parents may control what their children see on the internet. A simple logon page can display the tool's download/implementation information.
