Amazon Recovery?

Amazon has issued a statement to explain the controversial de-ranking of selected books, as reported by Amy Martinez in The Seattle Times.

The jury remains out on whether the exclusions, which Amazon explains affected more than 57,000 titles, were the result of a cataloguing glitch as Amazon maintains. Many still seem to believe that the current statement is more spin than fact and the debate continues on Twitter (#amazonfail) and elsewhere. Jane from Dear Author,… offers an eloquent explanation of why the #amazonfail controversy is very much an ongoing issue.

So, was this a glitch or has Amazon simply bowed to public pressure and reversed a behind-the-scenes decision to make certain titles and themes less accessible?
