The part so-often left out of this story (that Apple "stole IP from Xerox") is that the C-suite at Xerox got special considerations during AAPL's IPO, in exchange for access to their engineers in Palo Alto. From the POV of these former salesmen-turned-executives, it was fiscally worthwhile (they generally despised/misunderstood PARC engineers).

Xerox, of course, almost immediately liquidated their AAPL holdings (doh!).

Recalled from reading Dealers of Lightning at Xerox PARC (my favorite non-fiction book of the past few years).
