Again, this isn't about blowing open the doors to DARPA. Anything requiring a security clearance to view stays that way. This is about research that was already accessible provided you were either...
A) a student or faculty member of a university
B) willing to pony up the money to subscribe to the journal, which could cost hundreds of dollars depending on what you wanted.
As you can see, this is something that is easily accessible to China, Iran, etc. (unless they are the god of all cheapskates) but not to the regular viewing public. All this does is make this research more accessible to the American public. So unless you advocate that all of the research done in this country remain completely hidden from the public unless you have a high security clearance, your argument is pointless.
