I think people are upset not that there is an update, but that the issue is particularly bad. This isn't a hypothetical vulnerability or a UI glitch.
I know for myself the Apple apologetic posts also get annoying. (I'm not talking about your post) Yes things are more complex now, but Apple's software is particularly buggy, and they control their own ecosystem so it seems less excusable. And perhaps things don't need to be as complicated as they are, perhaps some of the software we are using could do with a ground up overhaul. Complacency doesn't nurture progress.
The phone was made weeks ago in China. How might someone suggest the latest OS be installed on a phone without releasing iOS, installing it to the phones, then beginning the distribution of the phone? That's illogical.
