As you may have read on the front page [http://www.macrumors.com/2016/02/05/error-53-home-button-iphone-brick/], Apple is bricking iPhone that have had Touch ID repaired with 'Error 53'. This violate the law, specifically the Magnuson-Moss Warranty Act of 1975. The law was specifically passed because in the past, car manufacturers were voiding the warranty for those who took their car to independent mechanics for repair.

By bricking the iPhones, Apple has gone beyond no only voiding the warranty, but also render the products unusable.
