Apple filed its formal response to the lawsuit initiated by Greenlight Capital's David Einhorn and blasted the complaint as being without merit and nothing less than an attempt to hold shareholders "hostage" by forcing Apple to acquiesce to a specific plan for the issuing of preferred shares that would primarily benefit Greenlight Capital. Having promised to review Einhorn's plan, the company found that Greenlight's proposal was self-serving, and that Einhorn himself referred to it as a "roadblock."
