Really, in my eyes, Intel has done nothing wrong. Business offer exclusivity discounts all the time, it is just a way of modern business. When you deal with suppliers, they all are going to give you discounts if you deal with them only and not their competitors.
Intel did not force anyone to not use AMD, they simply gave discounts to those how used only Intel. Nothing was stopping AMD from making the same offers, and I highly doubt they didn't make the same types of deals. The companies that accepted Intel's deal could have easily said no and used both companies.
This is really one of those deals where every other governing body accepts this practice because there is nothing wrong with it in the business world, it is a part of competition, but the EU suddenly makes it illegal and picks the biggest company it can to hand down a huge fine.
$1 Billion is a huge amount of money, a nice injection into a failing economy.
