I'm not sure I can come to the same conclusion from that page. 100 years later 4 major branches are still competing with the largest of those being <50% the value of the group as a whole seems like an ENORMOUS difference in competition compared to 100 more years of a Standard Oil monopoly. That's not even counting the dozens of minor company spin offs.

Even if they all merged into 1 again in the near future I'd still count that breakup as having massive long lasting impact.
