Platform Dependency Risk

Platform dependency risk is the vulnerability created when a company builds growth on another platform’s traffic, rules, links, ranking, payment path, or creator ecosystem. In No.200 电商三国之群雄逐鹿：腰挂公章、持剑拒签，以及 108 种死法, 蘑菇街 / Mogujie and 美丽说 / Meilishuo show the cleanest ecommerce version: their fashion communities generated value partly by sending users to Taobao, but Alibaba rule changes forced them into harder self-operated platform competition.

Key Claims

• Platform access can look like product-market fit while the underlying customer relationship remains owned by someone else.
• A rule change can convert a high-margin guide or affiliate business into a costly marketplace-building problem.
• Creator, livestream, and social-platform dependence can repeat the same pattern even after a company escapes the first upstream platform.
• Platform dependency is not always avoidable, but it needs to be priced as strategic risk rather than treated as free distribution.

Connections

• Local-Life Platform Dependency and Platform Intermediation Tax — related local-services versions already tracked by the wiki.
• 蘑菇街 / Mogujie, 美丽说 / Meilishuo, Taobao, and Alibaba — core ecommerce case.
• Distribution Led Product Building and Customer Pull — platform distribution can validate demand while still leaving control risk.
