Yeah organizations don't use YouTube for file access, that's just not a good way to operate a video department in a business. Also the quality is terrible and adding another set of reencodes will make it even worse.
But even if they did - I don't see why Google would care about these organizations. I expect anyone doing this is not expecting to get any views from the algorithm, is not bringing in many views or monetizing their videos.
To steelman it though, maybe Google cares if their monopoly benefits from nobody even knowing other video sites exist.
