Judge Denise Cote and the US Department of Justice, apparently.
"Hachette is not the only imprint to find itself under Amazon's thumb as the online retailing giant has begun turning the heat up on smaller publishers in the U.K., demanding terms that one publishing executive likened to a 'form of assisted suicide for the industry.'
Perhaps emboldened by its victory by proxy over rival Apple in the U.S., Amazon has been 'bullying' U.K. publishers to accept its terms, a representative from one shop told the British broadcaster."
You don't say. This won't stop until the judiciary overturns Judge Cote's decision, or the publishing industry is turned into a wasteland.
