When I worked at Yandex (aka Russian Google) there were two internal social networks. The official one, where work-related content was posted, and a secret anonymous imageboard known as "yachan". It was used to anonymously complain about various things or people at Yandex, but there were also some sexist, racist and other -ist posts as well. I wouldn't be surprised if Google has a secret chan-style imageboard too, hopefully it's less toxic though.

Why would anyone trust the anonymity of a site on an internal corporate network?

I just assume every keystroke I make and everything I do is being logged and reviewed by someone while at work. I don't even log into any of my accounts at work because I don't want my employer stealing my passwords and covertly monitoring my email and social media communication. To say nothing of actual camera surveillance.

Putting a lot of faith on the organization's leadership: it would befit them to treat it as anonymous, even if they have the capability of identifying posters. It would be an incredibly valuable window to honest feedback, although harder to pin down.

It's similar to how every employee understands that their manager has the capability of getting their corporate chat logs. It's one thing to have the capability and another to act on it. If a manager acts on it, it will almost always destroy any trust between the manager and his/her team. Within the organization, they will almost certainly be branded "that psychopath manager that reads chat logs" unless there was an exceptionally good reason to justify it (e.g. a legal reason).
