Not OP, but OP's point stands. If they can get special treatment, someone else's might be able to. The fact that it's a possibility means they must use it or risk being at a competitive disadvantage of a less ethical player.

Before an argument of "this justifies any type of behavior such as murdering your competitors' CEOs." There's a natural limit (albeit fuzzy) to what rules is in the company's self interest to seek a "special treatment". Relationships with gov't go sour, governments change, etc. What used to be "special treatment" might quickly transform into proof of wrong-doing against the company.
