I feel like nations should be only allowed to have providers block content based on GEO location from the visitors IP address. They have no right limiting speech in America.
Copyright protection is something I agree with like I think if Google gets a DMCA it's removed worldwide anyways since they host in the US too... So that's been the norm anyways. But just scary other nations might try to use this to further restrict non-copyright related things.
But then again not all nations view intellectual property the same. Doesn't some nations not recognize software patents? Like I heard they are harder to do in Europe than in the US before. Maybe you could get a US judge to order your European competitors website removed even if completely legal is their own country. Then same for trademarks, you may get a trademark in the US but someone might have a trademark in China. For example, iPad Apple trademarked in the US, but in China, they had to pay $60 million to settle a trademark dispute.
