I've read quite a bit about Amazon's recent (and ongoing) fight with book publisher Hachette, where they're trying to force Hachette to give them a better deal.
And apparently that's just a sign of things to come, because they're now working the same playbook (ie: screwing their customers) against Time-Warner.
If they're going to keep taking this kind of heavy-handed approach (and hosing their customers with lack of availability), that's not going to work out well for them. And it's an odd thing for Amazon to do, as they're a remarkably customer-centric organization. I guess we'll see.
