In a counterclaim against Electronic Arts' copyright infringement lawsuit, Zynga has made an allegation that could vastly raise the legal stakes. Zynga alleged in a legal filing today that Electronic Arts chief executive John Riccitiello proposed an anti-competitive "no hire" pact with Zynga's then-chief operating officer, John Schappert.
Citing emails allegedy written by Riccitiello, Zynga said that Riccitiello took the departures of EA executives for Zynga very personally.
