Two things about Michael.
While I respect him as an author, he did not voice his concern for his fellow authors when things were going down hill with his wife's publishing house, Ridan, through which he was published. As far as I know, to date, he still has not talked publically about Ridan's down fall or how the other authors were treated.
Secondly, in his statements about the Hachette/Amazon situation, he suggest a fair split of 35/35 between the publisher and author and 30% with Amazon.
I am not sure how he figures that he should get a equal split with his publisher when they have done all the work, plus, he got an advance. Six figures if I remember right. His publisher Orbit, a Hachette sub, did the final editing, the formatting to the various e-formats, the cover design, and got the reviews, not to mention the art work, and paid for the printing of the paper versions.
This is not to say Michael could not have done so himself, as he has in the past. But when he went with the big boys, he agreed to their terms and now he is whining because Amazon wants more of the pie and Hachette/Orbit is digging in?
As Michael said, even if self published authors lose the 70% from Amazon and are reduced to 35%, that is still more than what he would be getting from Orbit at 17.5% at his current deal with them. But I don't think he or many other SP are thinking about how much they have to spend to equal what the big boys do. Especially in time as Michael has had the time to devote to writing full time, and do less social media type stuff than he did when he was on his own, or with Ridan... That has got to be worth something...
