Why did zero-price markets strain antitrust?

The enforcement theatre (Unit 2's actors at work): 1. Detection: complaints, leniency applications, market studies, screening (procurement patterns), whistleblowers. 2. Investigation: information demands, searches and inspections (the dawn raid), economic analysis. 3. Decision: infringement findings with remedies (cease, divest, access) and fines; commitments decisions (the negotiated remedy — the authority binds the conduct without a violation finding). 4. Follow-through: monitoring compliance; penalties for breach of commitments. Nepal's model: the Competition Promotion and Market Protection Board — inquiry powers, orders, and the penalty framework of the 2063 Act (with the thresholds the Act and notifications fix); the advocacy function (guidelines, market studies) as the soft arm.
