That is a bit silly. The goal is to make anti-competitive and all negative conduct net-negative, not just unprofitable when caught. Otherwise, it is like a millions of dollars to none gambling, profits no one caught you, a slap on the wrist if you got caught. Not useful.

The sane calculaltion is to make the fine amount equals to (loss to society or profit to corporation) / (chance of getting caught). In some cases, I guess it can be argued that chance of getting caught is so small that the fine should bankrupt someone, but still we should not do it arbitrarily just because the target is a big corporation.
