The dollar value of a responsible report going up means more responsibility overall and less problem leaks, exploits, etc.
I would be equally happy to see any solution where the end result is increased security and privacy for everyone, even at zero bounty.
The problem being overlooked is that the actual cost of these exploits and bugs is paid by the people who had no say whatsoever in any matter regarding the issue. Any time a company is being "cheap" at the expense of regular people is a bad time, from my perspective.
Google has the power to limit the exposure of the people who use there products (and this isn't always voluntary exposure mind you) and is choosing to profit a teeny tiny bit more instead. At no immediately obvious cost to them, why not?
