If it's actually someone attempting to make money on a short or to benefit from a working relationship with a competitor, then a bug bounty program does nothing. No one can run a bounty program that pays out anywhere near as much as the information is actually worth to an adversary. Bug bounties work to engender a bit of good will among researchers and to provide some incentive to an otherwise neutral party to play ball. They don't mean shit to a hedge fund or a competitor in a multi-billion dollar industry.
