A lot of people have this fear. Amazon is a quickly expanding platform with a growing level of lock-in and immense power. This isn't good for the ecosystem - a dominant company can charge a premium, and choice is good.

We're doing just fine, thanks (growing quickly, differentiated product), but Amazon is aggressively expanding upstream and is going to continue to do so.
