CentOS does NOT support IBM Mainframe (eServer zSeries and S/390), so I think Red Hat is pretty secure being a partner with IBM. If your purpose is to scare Red Hat investors out of their shares, why don't you mention Oracle Linux, which like CentOS, is based on RHEL? If Red Hat can thrive and succeed where Oracle has struggled, I really don't think we need to worry about CentOS. I think I'll side with the 407 institutions and their analyst that own 95% of Red Hat stock. Now, go back under your rock and eat your snickers.
