haha, nice try. you can be sure that Apple will have one well written contract outlining the explicit performance (on ur end). selling to Zerodium obvi will not have much contra tual obligation. but dont forget who ur dealing with, blackhat 'groups' /havkers can be some evil fkrz and destroy lives in < 24hrs. u dobt want to sell a 0day and turn around and disclose it.? its not a 0day any longer. not advisable, trust me.

not only would you be out two pmts. + u will be prosecuted for distrbution and sales of piece of sofware that breaks multiple IC3 laws, + the outcome of that is that you will never be able own a compiter again, kinda stamdard with IC3 + transferring code across state lines is will make it a federal offense, automatically. along with being labelled a terrorist. (stupid yes, but true). + u will also have some dangerous blavkies(havkers, blackhat) out to destroy you.

again, this is imho only. but a strong advisement not to cross either party.
