Quite ironically for the GP, that's exactly what has happened in this case: a taxpayer-funded governmental organisation (NSA) has produced and released a public good for free consumption. They literally saw the toll bridge (IDA Pro), said ‘nope’ for whatever internal reason, built a new one downstream, drove their vehicles across it, and then said “hey folks, this over here is for you to use for free whenever you want”.
While I agree with your overall point, this isn't the greatest analogy, because a finite number of users are able to use a bridge simultaneously. A bridge with too many users is called a traffic jam.
