Basically what this amounts to is actively discouraging anyone in the technology sector, anywhere in the world, to do business in the USA.
You're clearly showing that what works and is successful in the rest of the world is an unwanted development in your country.
As someone is pointing out, this has reduced, almost eliminated the need for music piracy in a lot of European countries, which apparently isn't something you're interested in either.
On top of that, you're considering not paying the interest on the money you borrowed from the rest of the world.
This would of course end people betting on your country as a safe investment. Money flowing into your economy from the rest of the world appears to be something to avoid as well. Reducing the number of people in your country that can actually pay their mortgage or stay employed at all seems to be no cause for concern either.
The only thing I can really see you doing that would cause your status as an ally and first rate investment opportunity to go into decline any faster, would perhaps be to start senseless wars that ran on for decades mainly to keep the price of oil up.
