I mean it's a corporate decision to have all the work be hidden. There's few laws requiring that your company operate on a dark web but they all choose to.
I think if a pro sports team could figure out how to make it so the opposing team couldn't tell which one of their players is which they would choose to. Good luck running a shift in the MLB if you don't know if the batter is swinging lefty or righty.
Also I think pro sports teams is probably one of the best examples that public information doesn't make perfect decisions. Anybody that seriously follows a team can tell you about numerous bonehead (perhaps bonehead in hindsight) trades that their team made. Or players that were offered a deal well beyond what they were worth.
