I think what you're trying to say is that it was a calculated risk.
Perhaps Apple did collude and conspire, despite no evidence showing they did, but with Amazon's seemingly illegal monopolistic dumping tactics they wouldn't have been able to compete unless they also sold books at a loss. This isn't good for anyone. It devalues the books, the publishers, and when Amazon feels they have completely won they could then change the prices to be much higher (like they did the day Apple lost this round).
Apple now has a hold of the eBook market with quality digital copies that made Amazon go redo many titles that had spelling errors, formatting errors, etc., as well as getting Amazon to make their Kindle apps better. We also have publishers that don't see eBooks as a dead end with Amazon making them an inferior product with a demising value.
