This report examines how digital platform characteristics can either support or limit the success of modern business models. The analysis finds that strong network effects, connected networks, reduced multi-homing, and network bridging can help platforms attract users, collect valuable data, and expand into services such as e-commerce, subscriptions, advertising, and online marketplaces. However, platform growth can be weakened when customers use competing services, bypass the platform, or become dissatisfied with excessive restrictions. Apple’s closed ecosystem demonstrates this balance: its high switching costs and connected services strengthen customer loyalty and revenue, but its control over developers and transactions has also created regulatory and competitive concerns. These findings support the main reading’s argument that gaining scale is easier than sustaining a healthy and defensible platform network.
