All this is based on leaked documents and conversations, but I think that's a really big part of the problem. From what I can tell, the U.S. is more or less on its own on most of the more restrictive copyright policies. Australia is with them a lot of the time, in particular with technological protection mechanisms and I think with ISP liabilities as well. But the other countries, in particular Chile, New Zealand, and Malaysia, from what I can tell are onside with Canada, and the U.S. is kind of alone on these issues.
Those leaked documents are from the fall and they don't incorporate the latest round, so I don't know if our government caved to U.S. interests in that last round or not.
