With this rationale no monopoly should ever be investigated, broken up, etc. The whole problem with monopolies is that they actually harm the consumer by protecting their monopoly from encroachment by someone else. So yes people really think decisions are being made by a monopoly to protect their monopoly (and their profits). A chunk of those billions they have is actually money generated by these monopolistic practices. It's juvenile to imagine them sitting at board meeting and discussing "How can we protect our monopoly?", that's like saying the NSA is discussing by board meetings "how can we further invade everyones privacy?". But they most definitely are discussing how they can protect their market share and how to edge out competition.
