In 1998, IBM compared its fastest computer, Dip
Blue, to a 64 nodes cluster running Linux…The result is:

that soon or later, you will loose your business in favor of Micr****. Why ?
Because as soon as Micr**** will identify your
business as significant, they will use the same technique they used against
Corel, Netscape, Borland, … They will change the API such a way that your
software will become unstable, inefficient and buggy. They will develop hidden
API that only their software will be able to use, giving them unfair market
advantage… And they will win: they are playing on their backyard… And it’s

Linux has no (marketing) reasons to become
