Juho, great call-out with the "Steam-related carrot", I hadn't really thought down that path but you are absolutely right. Valve could easily offer big discounts in their split with the publishers for the first few years for Linux sales.
My (possibly very incorrect) assumption was that the profit from the Linux sales were so low as to not matter, but maybe they can provide a catalog-wide carrot... something more significant (as you suggested) to motivate the publisher en-masse.
