True, kind of — it depends on the definition of “market power.” There is a dominant market share test used by the courts, generally a market share over 50% is required while some courts require a much higher percentage. Here is the better explanation from the FTC: https://www.ftc.gov/tips-advice/competition-guidance/guide-antitrust-laws/single-firm-conduct/monopolization-defined https://www.ftc.gov/tips-advice/competition-guidance/guide-a... > Further, Apple has a 100% monopoly control of the iOS App Store. That irrelevant. Best Buy also has a 100% monopoly control of Best Buy stores. That doesn’t mean that Best Buy has a monopoly on consumer electronics stores, nor does Apple have a monopoly for computer app stores. True, Apple does have a monopoly when it comes to the iOS App Store.. but no more of a monopoly than Baskin Robbins has for ice cream sold by Baskin Robbins. That doesn’t mean you can’t by non-Baskin Robbins ice cream somewhere else, nor does it require Baskin Robbins to sell Hagen-Daz. If you want to be a sell your stuff at a store, you have to follow the rules of that store and pay the commission. Just like there are other places to buy computer software for a mobile device, there are other places to buy ice cream.
