There's a lot of evidence that sharing locally creates ecosystems that can more quickly uptake the research. There is a lot of local economic benefit from projects that share locally, because the best intellectual property walks on two feet, so the scientists can walk back and forth and discuss.
Also, other governments are sharing their results. The American government is very good. I don't think we should be wimps. We should be as competitive, and if we want to start companies, start them. Instead of complaining that other people are taking our stuff, we should take their stuff.
