PG should take steps to honour the copyright laws of other countries.
My reasoning is this:
Say hypothetically I started "Project Open" in a country with zero copyright protections.
Then by that country's laws, I can list Amazons entire kindle catalog, buy all their books and scan them, and make it open access.
And by the PG argument, ignore the laws of other countries that demand copyright protection for those books, until I get sued.
At which point I block the site for the countries based on IP address (as if proxies and VPNs and people who travel don't exist)
If someone did that, they'd probably be characterised as a pirate site and shut down by the FBI.
