Calling a vague group of entities 'Big X' isn't as useful as people think. It's not like there is a strong definition, or that everyone identifies the same with it. It's also not helpful to personify a vague group of even more groups (of business entities) and then assume they all had some concerted 'hand to play'.

It's possible that there is some emergent behaviour in markets with large companies and it might even seem like it's a single 'person', but it's not and it makes discussing specifics really hard. Perhaps it's an american thing, but it seems really odd looking from the outside in.
