Have you ever worked for a large company before? There's nothing management loves more than access controls. There are whole software products available, like Confluence, that do nothing but take good open source offerings like various wikis and make it so management has to set permissions for every user for every page to do anything at all. Then whenever you need to make a change it takes a week of meetings to get edit permission for the needed page...
Confluence is awesome, we use it in our company and every user can edit every page (that's how it's set out of the box!). This works great for us and our size.
To bash on Confluence just because your management has set restrictive policies seems a bit unfair.
Why would you expect every random employee to have the necessary access to expedite such a change?
It's 5 AM in Mountain View, they probably have to get someone out of bed. Also, I imagine they would like to figure out where it came from, which may or may not complicate the removal, who knows.
Seriously? I work at not so small tech company and here one of the managers/director/vp will take a call and the engineer will patch the changes. The call is specially easy is such obvious example of what should be done.
