Oh right and when Apple uses a proprietary BIOS to ensure that Mac OS can only be used on their hardware you of course see no way how this involves other hardware sellers.
That makes no sense whatsoever.
Firstly, unlike Apple, Rambus+Intel was not an exclusive license. AMD was free to license Rambus aswell, if they wanted to.
Secondly, DDR didn't even exist yet when Rambus and Intel signed the deal, let alone that they knew that AMD would choose to go with DDR, rather than also getting a Rambus license.
So trying to claim that it is a deliberate action to kill AMD is total nonsense.
If you claimed that Rambus was deliberately trying to kill DDR (and all other memory technologies), yes, I would agree with that.
But DDR and AMD are not equivalent. Nor are Intel and Rambus equivalent.
So your claim makes no sense.
Also, proprietary is not necessarily a nasty or evil thing. It's a shame that it has come this far.
x86 is proprietary aswell, now it is AMD's main reason for being the second-most successful CPU manufacturer in the world.
