And again the point of Titanous is that delaying the PoC provides a false sense of security. Saying "some time is better than no time" is the problem, you have a false impression that you have time while the fact that the PoC is not published does not mean it is not already used by some attackers. Delaying does not provide an incentive to people to update.
I agree that there is a tradeoff, but it is not a simple a you present it (delaying means giving some time).
