NIH has long required its grantees to provide open access to all articles produced using its funding.  Now, as described in this New York Times editorial, there's a bill in Congress that would kill this open access policy.  Offhand, I don't agree with the writer's suggestion that the principle should be "if taxpayers paid for it, they own it", in the sense suggested in the next sentence, that all work produced with government funding should be excluded from copyright.  But I do believe there should be open access to government-funded research.
