The government has shown time and again that it's terrible at investing. Most people/entities are when they're spending other people's money. This would result in the same issues as all government spending does - the powerful Reps and Senators will funnel money to open source projects in their districts and to their donors. We'll see a lot of open source projects in Kentucky get funded because of McConnell. Liberal & Democrat based projects will see little funding as Republicans block their funding. It would be a mess.
