I still have the old emails from Google Security in my mailbox. June 2, 2015 was when I received the first "received" email. June 3, 2015 is when I received the "triaged" email. June 4, 2015 is when I received the "filed a bug" email. You can see from the Bugzilla bug that it was fixed by June 5, 2015.
Nest really went down hard after the acquisition. They were a company who built a cool thermostat. That is all. Everyone who didn't work on engineering the thermostat seems incompetent, especially management. The UI which took them like a year to do once they bought Dropcam is much worse than the old Dropcam site. They never came through for Dropcam Pro buyers who they promised 1080p recording to (the hardware can do it, but they never made fixing it any kind of priority). They then go and slap those users and early adopters in the face by releasing the Nest cam with the same hardware with 1080p enabled.
The connected smoke detector is useless, since it's only useful in emergencies, and an app-connected thing which runs complex firmware is the absolute last thing I'd trust to save my life. There's a reason why sprinkler heads to put out fires are dead simple.
