The point is that notarization plays the same role for both platforms: checks whose purpose is to make sure that the software won't harm the user's device, unrelated to the App Store review process. Both platforms have an additional App Store review process which is significantly more strict, and the notarization process isn't supposed to involve App Store review for either platform.

When Apple denies notarization for bullshit reasons on one platform, it makes me highly suspicious of their motivation for notarization on all platforms.
