While it certainly seems beyond ludicrous to me, it did seem funny to think about if Microsoft bought Red-Hat, and IBM in kind bought Novell (acquiring rights to Mono along the way) what kind of a battle that would bring about.
I personally don’t think it would make sense for Microsoft to buy out Red Hat. I mean, what would they gain? The author says it would happen because Red Hat is possible an IP hot potato, but it seems silly to me. The thought that Microsoft would make some sort of a preemptive strike – I don’t know.
