> You listen using a service that abuses its users

It doesn't abuse me. It makes my life net better than it was before I used it.

This is a really important point for you - many people value what they practically get from a service - not abstract concepts of freedom.

What I care about is getting to listen to the book. I don't care about your DRM problems. I don't care about file formats. I care about the words that the author wrote going into my head. That's what I came for. If they give me that I'm a happy customer.
