Gotta love how the United States figures are a vague "0-1000". Maybe none, maybe 5. Maybe 1000. Can't really say.
I live in such a transparent place. Go go government.
I am assuming this is written this way for purposes of the chart. If you read the article, it says that the government isn't allowing Apple to disclose that information. In other words, it need to say 0-1000 or else the chart would be off.
