You got things the other way around it's not about the disclosure is about mitigation. If one contacts the corrupted major for a timed disclosure, he gets time to hide crimes or can continue being corrupted, but the press running the story only damages the major. If I run to the press with a vulnerability, everyone is empowered in exploiting it. Sure it puts lots of pressure on the devs, but devs can only work so fast, which creates a window of opportunity which damages both them and their users. A timed disclosure doesn't prevent exploitation that's already happening, but doesn't increase the problem by itself The desired outcomes in the two cases are different, and it's no surprise different strategies are optimal.
