Once again John Gruber shows he still doesn't understand why the Justice Department went after Apple for eBooks in 2013

Time for the Justice Department to investigate Apple’s music business.

The monoploy that the Justice Department sued Apple for was because they were price fixing ebooks in the iBooks store with the largest publishers, not because they had more customers for digital books than Amazon.

It is not serprising that Amazon can scale services better and faster than Apple; they have been doing that for years.
