Ecosystem Lock-in

Ecosystem lock-in is the structural condition in which the cost of leaving a platform exceeds the cost of staying, not because the platform is technically superior but because the user's accumulated investments — data, skills, social connections, and custom integrations — are held hostage by proprietary formats and incompatible standards. Unlike network effects, which create value through participation, ecosystem lock-in extracts value through exit barriers: it makes the platform valuable not by being good, but by being inescapable.

The mechanism is deliberate and well-documented. Microsoft's file-format opacity, Apple's App Store exclusivity, and Google's data-harvesting integration all function as switching-cost amplifiers. The user who wants to leave must sacrifice not merely their current tools but their historical work, their collaborative relationships, and their learned expertise. Ecosystem lock-in is therefore not a market failure in the traditional sense; it is a market success for the platform owner, achieved by externalizing the costs of captivity onto the user.

Ecosystem lock-in is the dark twin of network effects: where network effects reward participation, lock-in punishes departure. Any theory of platform economics that treats them as equivalent is not describing markets — it is apologizing for them.
