Don't blame it on intel, blame it on bad business/bad business practices.
Better management wouldn't have done anything to get sales through OEM's when Intel was threatening/bribing them to sell Intel exclusively.
The sales AMD did get in the K8 vs Netburst days were quite good considering there were large areas of the market where they could get zero penetration, due to what Intel did.
Having a much larger amount of resources, it was too easy for Intel to spend money on R&D and come out with the Core 2
AMD is not the only victim of it either. Look at Via, Cyrix, Texas Instruments. Only Via is selling x86 CPU's now, and they have a small fraction of the market share that even AMD does.
AMD has done by far the best considering the market conditions. Though via is still technologically competitive in the low-power segment, however, they still can't get much market penetration.
Now that's not the same thing. The end result may be the same but the intent is different and that is where you make the distinction.
If Intel didn't want a monopoly, they'd release the licensing of x86. And they wouldn't have made those deals with OEM's to shut AMD and Via out. and they wouldn't have designed their compilers to cripple non-Intel CPU's. what you're seeing is
PR FUD. Of course they don't want to be seen as crushing competition, even if they are.
Intel has a clever legal and
PR team. Still, I don't think AMD has broken the cross-licensing contract.
