They presumably also configure their command and control to only persist if it is one of the designated targets and wipe all traces if it is not, so even forwarding the attack payload would probably not do anything. You would need to determine you have been compromised and then reverse engineer the exploit so you could replace the command payload with a irreversible bricking operation to do what you suggest.
At that point you might as well spend the $5M-$10M to develop the entire attack yourself. If you are a competitor to Apple spending $10M to completely destroy the $2.7T Apple is literal pocket change; too small to even show up on your financials.
