In July this year, the US Congress had questioned Apple concerning antitrust and competition. Today, documents from the hearing has been released.The Judiciary Committee of the House of Representatives is exploring the technology industry, looking for exclusive business activities. Lawmakers sent a series of questions to Apple, as well as Google, Amazon and Facebook.Apple told Congress that it doesn't make a profit from repairing an iPhone or Mac and only sells genuine Apple parts to companies with trained technicians to install them.Congress however, asked Apple “why they prevent independent repair shops from purchasing accessories and repairing Apple products? Is this a way for Apple to overcome competition and extend its monopoly into the repair market? ”Feedback, Apple said their products are complex machines, very high production techniques. And they need trained technicians to fix them. Untrained technicians may not follow safe and appropriate repair procedures and may result in damage or loss of safety.Every year, since 2009, the cost of providing repair services has exceeded the revenue generated by repairs. Apple says there's no reason to want to monopolize an unprofitable business.However, Apple does not refuse the service of repairing a device showing signs of repair from a third party, Apple told Congress. Similarly, Apple will still repair machines with non-genuine parts and components, if they can be repaired.
