Project Zero researchers don’t take bounties, to my knowledge.

Nor have they been ever offered one, to my knowledge: https://twitter.com/i41nbeer/status/1027339893335154688. I'm actually not sure Apple has ever paid a bounty for anything that wasn't a web issue…

If memory serves, they've been offered but the bounties are always been given to charity.

I'm guessing that's a policy/requirement of Project Zero as, presumably, the P0 folks are making "enough" already.
