Do you own a .com domain? If so, the U.S. government can seize it at any time. The same applies to .net, org. .biz, and other top-level domains (TLDs), and it doesn't matter where you live. You could reside half way around the world. You could be hiding out in Vanuatu, an island nation in the South Pacific ocean that you probably never heard of, and the U.S. government could still take control of your .com website.
VeriSign manages the .com domain (amongst others), but it doesn’t really OWN it. There’s a whole host of ICANN regulations in the way that keeps VeriSign from being able to take down any website it wants, anytime it wants. It’s looking for relief for some of those restraints in an appeal to ICANN that is first and foremost about responding to governmental takedown requests – at least on the surface – but contains slippery verbiage that could cause headaches for website owners around the world.
