Honestly comments like this really depress me. Maybe consider why you immediately have knee jerk thoughts about why this is bad or hypocritical and negative and reflect on that
He does not need to sell his anti-Amazon book on Amazon, it is laughably hypocritical and goes against his entire message in his Twitter announcement:
> it's an action-oriented look at how tech and entertainment monopolies steal creators' incomes, with detailed, shovel-ready plans to unrig creative labor markets and pay artists
That's not hypocritical. A hypothetical example of him being hypocritical would be if he owned an comparable business to Amazon and enacted the same practices he complained about Amazon doing.
> You can pre-order the book on Amazon. It’s like a PETA selling furs to support their anti-fur campaign.
