It seems most commenters want to interpret this as a threat, or as a way to discourage use of FOSS by government. I don't think it is either one. The US government isn't a monolith, it's thousands of semi-independent fiefdoms all doing different things, and some know what they are doing and others have horrible security practices. This seems to be one of several efforts to fix that. Looks to me like it will wind up making more money available for developers, mainly outside government, to audit and improve important free software that the feds are currently using. Unfortunately because of the way that government contracts work, companies that are already experienced at doing government contracts might wind up with the bulk of the money. But it isn't going to make things worse and might actually make things better.
