The fine should definitely NOT go to AMD
Competition law does not work that way, nor should it.
Competition Law is meant to detect harm to the CONSUMER, not to competitors.
Preventing a competitor from doing business is bad for consumers if it raises the price, or decreases the quality, in the long run.
For this reason, the anti-competitive companies are fined and the money goes to the representatives of the consumers, that is, the states.
The competitor can also sue for damages, but that's a different point entirely, and you should not get confused between the two.
It would be of the utmost ultra-liberal stupidity to say that when customers are hurt, companies should get the money for it.
*I* ended up paying my processing cycles more because of the reduced competition, so *I* should get the money back, for instance by paying less taxes thanks to the billion the states get back (or to the billion less in deficit that I'll end up paying for because governments can't control spending, but at least, they'll borrow one less billion this year, and that's an other issue anyway).
I'm very happy if, in addition to that, AMD investors (through AMD itself) can also get some money from Intel investors (through reduced Intel earnings), but I fail to understand people here who would consider the harm to society should be ignored and only the harm to AMD investors should be considered.
