I think the first article mentioned it (can't remember if here or elsewhere but I think it was here a day ago or so). Microsoft was found guilty of this very same practice. The two big profile EU cases where/are interoperability and bundling but MS has been in US courts over OEM fixing.
It was the same old "if you sell systems with no OS or not our OS, we will take away your deep volume discount so you can't compete with all the other OEM that play by our rules."
