So now we have laws in the US against arrogance? We can penalize people and companies for being impolite, or do they need to be really big assholes? Does being egotistical count?

Just kidding actually, I like the AMD Intel reference, but hey are branching out into areas that are grey also. Let's remember that aside from the true blue connentation that monopoly laws were created to keep competition alive and robust, and to make things better for the average joe, A huge part of the influence on anti-monopoly laws was aimed squarely at the railroad barons and their companies by the government because the government was afraid they had too much power over the economy. The laws were put in place to protect the governments interests as well, not just the little guy.
