You're latching onto this specific case, perhaps because you have some connection to it, but I'm talking about the general principle here. In general, it is not unreasonable to assume that if a vulnerability has been found by two parties in rapid succession, there may be a common factor involved, which may mean that other parties will also find it in the same time frame, and that an extra day may therefore be very significant.
Obviously most serious security bugs don't sit there for years, then have two groups discover them at almost the same time, as seems to have happened in this case, and need half the known Internet to update their systems as a precaution because no-one really knows whether they've been damaged by the vulnerability at any time over the past couple of years.
ROTFL. Yep, large corporate bureaucracies, they ALWAYS do exactly the right thing, in a matter of hours.
If it's that funny to you, why are you defending giving them a day of advanced warning? Some of us did have a patch rolled out within a couple of hours of the public announcement, but presumably we could have had the patch rolled out a day earlier in the alternative situation. Once again, in this case, one day in two years obviously isn't that significant as we're all going to have to assume keys were compromised and set up new ones anyway. But if this was something that only got committed three days ago, it's a different story.
