Earlier quoted context omitted.
You may not know how to follow logic. No one is saying that Epic are doing bad things in order to maintain their monopoly position. Epic doesn't have a monopoly on any market. People ARE saying that Apple are doing bad things to maintain their monopoly position, and others are justifying that by saying that "running a business is expensive" as if that justifies a monopoly or monopolistic actions.
If Apple has a monopoly on the iOS App Store market, then it follows that Epic has a monopoly on the Fortnite add-on market, right?
> the question as to what is anticompetitive and what is simply good business changes as a business scales. A small business can generally be as anticompetitive as it wants to be, while a much larger business is much more constrained in how anticompetitively it can act
The word “monopolize” is used in a specialised way in antitrust; it doesn’t encompass every exclusive right of sale, because that would disrupt many small businesses and law is intended to prevent huge businesses from dominating the economy.
