Ballmer sees free software as Microsoft's enemy No. 1 "...Ballmer a few years ago summed up Microsoft's competition by using the acronym NOISE -- Netscape, Oracle, IBM, Sun and Everybody else. Netscape Communications Corp., now owned by AOL Time Warner Inc., isn't on Microsoft's radar anymore. Ballmer now talks less about Sun and Oracle Corp. and more about Linux and IBM's WebSphere program, which works with Linux."
