I always thought IBM would be the most fitting company to buy Sun.
IBM is facing the exact same problem selling AIX boxes as Sun/Oracle and HP do selling their Unix hardware and OS, so why would IBM have been a better fit to buy Sun? I think Sun was (mostly) acquired to prevent Java IP being sold to other, more nefarious parties (such as MS or patent trolls). Both Oracle and IBM were (and still are, though to a lesser extent) heavily invested into the Java ecosystem. Sun OS/Solaris…
IBM Services do a lot of support work for Solaris around the world.
But yeah, other than that it doesn't make a lot of sense.
