They are you. You is they. It’s one company with one goal — keep companying.
The idea that ever “department” should access every other department’s data through some bespoke interface that the latter department maintains might work at some corporate behemoth, but at almost all other scales is absurd.
I don’t know that this is a problem specifically of the US or higher education, just humans. Humans want to have the best, to be the best. There’s only so many “bests”. When competing with millions or billions of other people, the odds you are the best are very low indeed.
I think it was less painful pre-internet, pre-globalization, where you only had to be the best in your town, or your state, and that was pretty dang impressive. Now if you aren’t the best in the world what even are you?
