I think it would be more like if I get to find out that Guy A wants to buy some widgets before you get this information. I also get to find out that you're selling widgets before Guy A gets this information. I can buy widgets from you for cheap because you don't know that there is a market yet. I can sell them to Guy A for expensive because he doesn't know there are plenty of widgets to go around. On the face of it, there's really nothing wrong with this - too bad for you and Guy A that you don't have access to the information that I do. But I think the concern is that I can use my position to control the markets, or that everyone will lose faith in the game and stop playing.
