While what you say is true, it is all legal. If legal it is not corrupt.
Do you not believe that what is grossly immoral can also be described as corrupt? That stating something when you know something else to be true, and doing so for an unstated political goal, is not corrupt?
Methinks your definition of "corrupt" is far too narrow.
The media is both self serving AND corrupt. Corrupt beyond description.
One can be corrupt without breaking a law. Corruption typically refers to actions that conflict with morals, ethic, or understood proper codes of behavior. If members of the press, on one hand, espouse fairness, objectivity, non-bias, etc., but, on the other, act in completely opposite ways, they can be considered corrupt.
