i guess at minimum it's worth asking how many major hosting providers have been fully patched at the time of disclosure. in addition to browsers and OSes.
You don't "think infosec". If I'm an attacker and I notice both amazon and azure rebooting all their systems I know something is up. When I see that both Microsoft and Redhat employees are working overtime it gives away more information. All I have to do is crack on of their patched systems and I can bin diff it and figure out what is up.
Then I sell it off to blackhats before the rest of the world is aware.
