It was even more fundamental than that. A foreign manufactured product could have the 'right to re-sale' by the owner effectively revoked. If the ruling had gone the other way, a lot of manufacturing would have moved out of the USA as the manufacturers would have had a lot more control over resale.

In summary, as long as it was manufactured legally anywhere in the world then you can damn well do with it what you like after you have bought it :)

What is more interesting is his comment on the “You Own Devices Act” (YODA). In the Internet of Things age, you may own the physical device but the licence to the software running on the device could be argued, is not transferrable. YODA enforces first sale rights to such devices making the software 'licence' transferable as part of the sale.
