Senator Charles Schumer (D-NY)wrote an editorial for the Wall Street Journal about the US Department of Justice's lawsuit against Apple over book-selling practices. I'm sure there must be some explanation for this lawsuit but it eludes me.
As I understand things:
Amazon had a chokehold on digital distribution and was gleefully ramming it down the publishers' throats.
Apple, and others, entered the market and gave publishers more control over how they sold their books.
If anything, it seems that Amazon is the one being anti-competitive. It looks like Senator Schumer agrees with me.
