You think there’s no content that needs a warning, but others may. And that’s kind of the point (people may be hurt remembering civil war and slavery and people may be hurt knowing that the content supported the construction and operation of concentration camps, etc).
I’m not concerned with being happy, I’m just trying to understand the value system that Disney is using to make these notices.
I don’t think it’s potential harm to the viewer, but maybe we’ll never know. One theory was that they were trying to atone for previous harm caused while making stuff (eg, using the confederate flag when they shouldn’t, etc).
I think it is sort of whataboutism, but only because Disney is literally whataboutisming their own content library. Usually I don’t think it applies since it’s not relevant that Y is bad for whether X is bad.
But in this scenario, Disney has stated that they reviewed and updated content. So if Disney reviewed content and didn’t find it preroll worthy, it gives a signal what Disney thinks is relatively bad.
