The Federal government pays a lot of money for research and development in a lot of areas, architecture, bridges, roads, jet engines, custom ASICs, etc etc. I used to design custom racks, brackets, conduit routing, power/heating/cooling systems for electronics. Think Humvees with quarter racks to a full mobile data center. It eventually got to the point where we were only doing something new/innovative every 3rd or 4th deal. Every other deal was use the bracket designed for A, the rack from B, the generator from C, etc. If we had to release those cad drawings we would have had no competitive edge. If they're saying code should be reusable across agencies and parts should be made open, when stop just at software?
