Makes sense. There are some academic papers (I think one by Ross Anderson) which state that steganography relies on there being some randomness in the data you are hiding the message inside. So, to make the bandwidth available for for steganographic data hiding as large as possible, those needing to conceal data need incentives for innocents to publish files constructed using as large as possible quantities of random bits. It looks like Stable Diffusion is providing this incentive!
