As I see it, the problem with Amazon stems from the fact that though it started out as a bookseller, it isn’t anymore, not really. It sells everything now, and it sells it all aggressively. Maybe Amazon doesn’t care about the larger bookselling universe because it’s simply too big to care. In a way it’s become, like the John Candy character (minus the eager, slobbering benevolence) in Mel Brooks’s movie “Spaceballs” — half man, half dog and thus its own best friend.Like just about everybody I’ve talked to about it, I first attributed Amazon’s price-comparison app to arrogance and malevolence, but there’s also something bizarrely clumsy and wrong-footed about it. Critics may appear weak today, but they may not be tomorrow, and if the wind shifts, Amazon’s ham-fisted strategy has the potential to morph into a genuine Occupy Amazon movement. And even if the company is lucky and that doesn’t happen, what has it really gained? The fickle gratitude of people who will have about as much loyalty to Amazon tomorrow as they do today to Barnes & Noble, last year’s bully? This is good business? Is it just me, or does it feel as if the Amazon brass decided to spend the holidays in the Caribbean and left in charge of the company a computer that’s fallen head over heels in love with its own algorithms?
