The first two are simply embarrassing. Google paid 3 Billion for this stuff? Does anyone do QA any more? Especially for a device you use for a security purpose, you'd think bugs like this would be not only found, but designed to not happen in the first place.
I know you're implying that they don't care anymore, but I think over-working leads to fatigue and rush jobs/corner cutting, which is a great way to end up with security flaws.
That's because Tony Fadell made them work on the weekends. If you're forcing your employees to work on the weekends, on a regular basis, then something is very wrong - which probably explains why he's no longer at Nest.
The third flaw is endemic to Wifi, and it's so easy to execute with off-the-shelf tools that the more esoteric attacks hardly make the camera security any worse.
Anyone that cares about security uses hard-wired cameras.
