After reading through the comments quarreling about whether Qualcomm and Apple are acting within their rights to charge monopoly-sized rent where they can, and do, it's hard for me to fathom the depths of confusion Americans are reduced to whenever these topics come up.
First and foremost: when you are as big as Qualcomm and Apple are in their respective spheres, you don't need rights. You have POWER, which is far, far better, especially when you can use it to extract money to buy more power with.
Rights are for little people. Qualcomm has been at this for decades. How long can you get away with just parking your car in the wrong place?
Second, when you talk about abuse of monopoly power, it makes no sense to look at it from the standpoint of the monopolist. Everything is stacked in their favor. The important question is, what can the little guy do? Not other companies, even though they complain most effectively (like Apple or Intel complaining about Qualcomm), or even small ones that can't. They would all love to be monopolies too, and sometimes are. What matters is, what is the experience of somebody who got an iPhone for her quinceaña, or of the farmer stuck with a busted John Deere tractor?
Each is obliged to pay a huge premium -- for software, or repairs -- because the 400-pound gorilla can force the matter. The fact that somebody else has an Android phone or an IH tractor doesn't help either of them. Each is stuck with what Apple or Deere is willing to let them have.
The law doesn't need to define a monopoly: only a monopoly can exercise monopoly power, so it suffices to look for that happening. Any monopoly not visibly abusing its monopoly power has nothing to worry about, because nobody can tell.
Anti-trust law doesn't make it illegal to have a monopoly. It just says that if you choose to make one -- and every monopoly chose it -- different rules apply. The law defines lots of rules, but the DOJ has chosen to ignore almost all because of a lately fashionable notion promoted by Chicago-school economists that nothing matters except high prices. Under the law there is a hell of a lot of monopoly abuse nobody at DOJ will even look at, that have all kinds of deleterious results. Anybody who wants to do anything about any of it gets mobbed by defenders of monopolists' rights.
And that's where we are today. Qualcomm got in trouble by making things unpleasant for other 400-pound gorillas, and we get to watch. Offenses against us are entirely ignored, and now people insist that's normal and right, law or no law.
