At a smaller, less corporate company the engineer/public comms person dividing line would not be so ossified the divide couldn't be bridged when the situation called for it.
I think the broader point here is that they (whomever they is) don't think the situation calls for it. That's why they said the next update would be on Monday on Friday.
You may feel that's a bad decision, but I doubt that people are in a panic because they can't push out an update that would not be noticably different from the last one.
>Just to clarify, what should this update contain?
"We're working on it", possibly an ETA for a fix or some details. Technically it's fluff but people are not machines and the update is for people. We like the feeling that people are working on a fix, that people care and that the end is in sight. It makes the situation less stressful and, as for why Google should care, less stressed engineers won't bad mouth Google as much after the fact.
I think this comes down to the two outages being not at all similar. An s3 outage affects practically every Amazon customer. This affects a relatively small number of go customers.
And I'm confused about what was good about that response. That article is about how the s3 outage caused so many issues that Amazon couldn't update their status dashboard to inform users at all.
