What could the DOJ investigation lead to?
It could be anything from no action at all to a lawsuit. In between is the possibility for discussions with the companies to modify the deal in some way that would address concerns that it hurts competition. With that route, the companies would sign a consent decree overseen by a court. If it does come to a lawsuit, it’s a civil case, so nobody at Yahoo or Google would be going to jail, if they lost the case.
