While I understand your take on Amazon from an emotional viewpoint, dislike of big, almighty corporations, from a marketing and promotional perspective an ebook on Amazon can reach lots of people and that´s what you want, right?, to spread the message.
If I search "earthship" on Amazon, your book is number two, right after Reynolds.
That´s how the world works, your ebook on Amazon, your video on Youtube, that´s how people find you.
And from a spiritual viewpoint it´s also a great chance to work on raga dvesha, likes and dislikes. 😘
