Earlier quoted context omitted.
Bounties exist for security bugs to make it more profitable to report the bug than it is to exploit it, or to sell knowledge of it to those who would. A buy about opening 70 copies of Visual Studio is unlikely to be very profitable to exploit.
Repectfully, you are incorrect that bounties exist to make it more profitable to disclose than to sell. Corporate bug bounties will never be able to compete with the budgets of nation states. They are basically a way of paying respect for a moral approach to a discovery that takes great skill.
If I have to choose between 5 year's wages with a 90% chance of going to jail for a very long time vs. a month's wages as a bounty and a 0% chance of going to jail, I'm going to pick the bounty every time. I think a lot of people would agree with me.
As discussed further down in this thread, raising the value of the payout or lowering the possibility of being caught makes the other side more attractive.
(of course, I would choose to disclose every time, because I'm just a good person.)
