You seem to imply that before the iBook store there was a competitive situation. Can't agree. Amazon was guilty of predatory pricing in my opinion and this in itself was anti trust. Now, I agree two wrongs don't make a right, but to sanction Apple for manipulating a "market" where it wasn't possible to profit from sales is wrong. If the anti trust bodies had sanctioned Amazon for its pricing policies, and a viable market had emerged, then there would have been no need for the publishers to try to protect themselves from being beholden to a single outlet.
How can Amazon be predatory pricing when it makes a profit from selling ebooks?
It's called a loss leader. Sell some popular books at cost or below cost, sell 95% of other ebooks at profit. End result: overall profits
Supermarkets have been doing this for decades.
Apple is using this "loss leader" pricing right now for its iBookstore on a few ebooks. Apple could have competed with Amazon on prices if it wanted to. Buy ebook at wholesale like Amazon did. Have a sale on a few popular titles and sell the rest at profits.
Apple is better suited to this strategy than Amazon since Apple is many times more profitable and have a bigger cash hoard.
But Apple wanted the 30% margin. Wholesale competition means the margin would be very tiny. Best way to get the 30% margin is to forced Amazon and B&N and other ebookstore to take the 30% margin too.
When retailers are guaranteed 30% margin and no price competition, who lose out?
Consumers
That's why the publishers have agreed to pay something like $52 million in restitution for the ebook price fixing.

So in order to compete with Amazon, Apple should have been prepared to match Amazon's price. Even though Amazon in many cases was selling at break-even or making a loss?
The game Amazon is playing is to go for growth and worry about profit later. Wall Street gets it: Amazon is priced for MASSIVE growth in the long term. They will do this by destroying competition and preventing competitors from entering the market. Once they achieve this, they will own the publishers and be able to strike any deal they desire. They will also be able to charge the reader whatever they like within reason.
What law has Amazon broken in their quest to destroy competitions and preventing competitors from entering the market?
Amazon can't be guilty of what they haven't done yet. I.E. raising the price when they have a monopoly.
In fact, when Amazon have 90% of the ebook market and they jack up the price, buying it at $7 wholesale and selling at $12, what to prevent competitors like a guy in his garage can buy $7 wholesale and sell it at $9.
Amazon price: $12
Competitor price: $9
Look at Apple domination in digital music selling at $1.29.
Amazon competed buy selling a lot of popular songs at $0.99, less margin but increase market share. Some did switch from Itunes to AmazonMP3.
