Maybe force tech companies to sell their products and services at cost + 20% markup. /sarcasm 1. What happens if the company has too many spare parts and wants to sell at 0% markup? Can they do that? 2. What happens if the spare parts factory burns down in an accident? Is the company legally obligated to rebuild the factory? What are the terms for how fast must the company rebuild the factory? Does the company need a backup factory to produce spare parts? 3. How long should the company be obligated to provide spare parts? Should this duration be applied to all electronics?
