It's not censorship when they give you the option to opt out and surf porn to your heart's content.
As I already pointed out, it IS censorship, because PUBLIC hot-spots will still have the censorship. You won't be able to go down to your local library and get uncensored internet access.
Also, the internet is not within the governments jurisdiction. If they are allowed to put mandatory censorship on your internet, then in the future they will also be allowed to take away your right to opt-out.
The internet is just communication. This is like the governemt installing a language blocker on your cell phone, so when you're talking to uncle Dirty Mouth it bleeps out his "F--k, s--t and c--t"... What gives the government the right to do that?
