I agree with the OP that we need to be informed in order to have the conversation. But..... You have the main point here. The whole premise of monopolies is that monopolies dominate bottlenecks, and use them to generate outsize revenue and protection from competition. Facebook doesn't make money directly from whatsapp. It can be used to generate data for FB's main advertising business. Most importantly, it helps maintain facebook's dominant position in social media. That position is revenue generating. I agree that understanding the mechanics are important. But, we can't keep treating monopolies as innocent of monopolistic practice until proven guilty. The reason we have antitrust in the first place is that monopoly positions lead to monopolistic practices. We need to assume monopolistic practices exist in the case of a monopoly. When one monopolistic practice (eg amazon marketplace or adwords) has been proven in court, this should be treated as proof of monopoly, not a standalone violation. Same with the CCs.
