It turns out that corporations are not people, but are instead made up of people, and some of those people - especially when working together with lots of other people on projects - are prone to making stupid mistakes that make the corporation itself look stupid even though knowledge of what was being done might not have been purposefully present anywhere among the people responsible for the error.
I mean I've worked on projects where somebody got in some content and I said - hey you should probably vet that content and they said oh, oh I think it's okay because of X, and I said well are you sure because, well ok I'll check I asked and they said they think X is fine. Ok well whatever, I'm sure not going to fight over this thing for the next two weeks just to end up looking like a jerk at the end.
