Platform Subscription Economics

In an era where digital ecosystems rely on recurring revenue, analyze how subscription-based offerings influence value creation, retention, pricing, and competitive strategy. Compare at least three sectors (e.g., social platforms, cloud services, streaming or SaaS) in terms of design choices, price sensitivity, churn, and feature trade-offs. Discuss potential regulatory considerations focused on consumer protection, data usage, and market power. Propose a framework for evaluating when a subscription model is likely to be sustainable and beneficial for both providers and users.
