Good job intentionally ignoring the point and drawing a false conclusion for the sake of dishonestly pretending to debate:
High
barriers to entry such as large upfront investment, notably named
sunk costs,
requirements in infrastructure and exclusive agreements with distributors, customers, and wholesalers ensure that it will be difficult for any new competitors to enter the market, and that if any do, the trust will have ample advance warning and time in which to either buy the competitor out, or engage in its own research and return to
predatory pricing long enough to force the competitor out of business.
Apple exclusively requires you to have your app on the Apple App store (aka requiring the use of Apple's infrastructure), for the app to be available on one of them most used devices in the world (that has a freely available API). You know this, but you choose to blindly defend a multi-billion dollar company's anticompetitive business practices.
