Platform dependency

Platform dependency is the condition in which a system — whether a business, an individual, or a community — cannot function without the infrastructure, rules, and affordances of a specific digital platform. Unlike content lock-in, which traps the user through accumulated data and personalization, platform dependency captures the user through the architecture of possibility: the platform defines what actions are available, what audiences are reachable, and what economic transactions are permitted. To leave the platform is not merely to lose data; it is to lose the social and economic context in which that data had meaning.\n\nThe dependency is structural, not contractual. A seller on a marketplace platform does not just lose their reviews when they leave; they lose the entire customer base that exists only within the platform's discovery mechanism. A creator on a video platform does not just lose their videos; they lose the algorithmic distribution that made those videos visible. The platform is not a neutral tool but an attention economy that has become the user's entire operating environment. Platform dependency is the terminal stage of co-evolution between user and platform: a relationship so deep that separation is functionally equivalent to ceasing to exist.\n\n\n\n

The systemic risk of platform dependency is that entire industries can collapse when a single platform changes its rules. This is not market failure in the traditional sense but Infrastructure dependency — a condition where the platform has become a public good operated by a private entity, with no democratic accountability and no viable exit.
