If shipping a specific device configuration to the US is illegal, Motorola should not ship this specific device configuration to the US.
I do not think our parent is suggesting otherwise.
AFAIK Motorola and GrapheneOS are not merging, they are getting into a partnership. They do not have to think or do exactly the same.
Apple can comply with both CCP and US demands at the same time without a problem. I am sure Motorola can adjust their services to the markets they are working in, as well.
Motorola is pretty much only present in US these days, why would they build a product that can't be sold in their primary market?
Demanding that OSes outright violate the law because you disagree with your own elected government is pretty insane.
