As of today (August 23, 2013), Apple is guilty of having conspired to fix the price of ebooks. The company is, however, appealing the verdict. Therefore, there can still be some debate as to whether Apple is truly guilty. If the question is whether the judge should find Apple guilty of price fixing, that is a matter of opinion.
Apple was found guilty on July 10, 2013 of having conspired with five publishers to raise the price of ebooks. The publishers had been unhappy with Amazon’s discounting of their books and began to conspire (the judge found) to fix prices. Apple joined them in the conspiracy and also provided the publishers with an alternative way (other than Amazon) of selling their books. After Apple did this, the price of ebooks rose. Accordingly, the judge found that Apple was indeed guilty of conspiring to fix prices.
However, there are some people who do not think Apple is guilty. They argue that the publishers conspired to raise the prices but that there is no evidence that Apple was part of the conspiracy.
