If this were a vulnerability that allowed people to activate Windows without paying Microsoft:
a) There would no complaining that Google gave them only 90 days notice because there would be a patch ready to go within a week.
b) Nobody at Microsoft would be saying, "Well yes, the patch is ready but we really should wait until 'patch tuesday' to deploy it."
On the other hand, if this were a vulnerability whose disclosure would cost Chrome market share, I'll bet'cha Google could have found it within themselves to wait a couple of days longer.
