Perot bailed on EDS, and went on to found Perot Systems as a competitor. Did pretty well too.
He had good reason. He sold EDS to GM and got a place within GM where he could still run EDS an independent entity. But Perot clashed wit GM's management, which basically wanted to suck EDS into GM's management mode, and we've all seen how good GM's management is. Basically, old, backwards-thinking, short-sighted management was going to crush the dynamic management of EDS that Perot had thought he could preserve under GM.
He made a big stink and was quietly bought out by GM with motives straight from Beckett, "Who will rid me of this troublesome priest?" Not bad, in all Perot made 3.2 billion off of the EDS sale.
BTW, bit of trivia, Perot mostly financed Steve Jobs' NeXT company, which made the computers the WWW was invented on, and whose operating system was the precursor to the current Mac OS X.
