If someone is violating US copyright laws, thats not censorship; its prosecution. There is no inherent right to break the law, therefore it does not enjoy freedom of expression.
You are correct - but the question involves more the techniques of enforcement. That is, do things go through the normal courses of courts (as opposed to a court order) , trade commissions, etc. - or does Big Government need to hire more people so they enforce commercial contracts?
As the analysis says, on the internet "foreign" and "domestic" tend to blur.
IMHO, these are issues which we predicted at the start of the commercial internet - that Big Government would see some of their power being lost to the internet and struggle in every possible way to stop it. Power does not like to be challenged.
The intentions may even be honest - but to assume that our representatives in Congress and other branches of government really understand this stuff would be a reach. In general, less regulation beats more regulation....when it comes to copyrights especially.
Taking a small example, my forums probably contain many thousand of copyrighted images inserted and linked to by posters. Big Government could order me to remove them all. How would I even find them (I have 70,000 images), let alone replace them or take them down.
Why not boil this down to a solution for the real offenders who corporations are probably going after? Those being the pirate sites for movies and music and software? This could probably be done under existing law or with a much less invasive law than this.
It's always interesting how "small government" folks often turnabout when any authoritarian/corporatist issue is on the table. Then they go back to bashing the attorney general the next day!
Netflix and itunes are proof positive than when paid solutions are available and reasonable, most of the public will not pirate. Problem solved.
