There isn't though. This is just voice control of existing things people are already doing through Amazon. This is data they already have. Is data inherently evil? I don't understand how there is some significantly different privacy concern of using Amazon services (wish lists and purchasing things) via voice control than via their website or app.
There are many legitimate privacy concerns with ever-listening devices in your house, but having "data" from people directly using existing features of a company via voice instead of mouse clicks isn't really one of them.
