For one thing, it doesn't looked like Google/Android did this at all. As others have said, it looks like someone has falsely contributed to the map and got past the review. Such an examples is pointed out by andrea_s here[1] (it is around the same area as the original link).
If it were believed that this was an official work by Android, I bet the comments would be much different. However, as it does not look official, the comments in this article cannot be compared to the comments on an article relating to what you describe.
Google published it. Whether it was a paid employee or volunteer vandal doesn't really make the organization look worse or better.
(Personally, I don't see any reason to be outraged about it, and wouldn't be surprised if they don't see this as a reason to even bother about their review process. If it is a volunteer they will ban them, if it is an employee they will hopefully explain that they don't get to make a similar error of judgement again, or perhaps fire them.)

It looks like a user had enough reputation to add things without review.
Though my excuse at least is that "Apple is known for their massive review process and locking down of everything - this can only be intentional" if it was Apple.
It's more an expectation from the company - I wouldn't even be fully surprised if it was a cheeky Google employee who did it. Would probably get laughs as PR frowns and makes the map team remove it.
I'm an iPhone and Mac user and still the prank made me chuckle.
