I don't understand why Apple is still considered an American company today
In fact, it matters so much that most western countries require the country of origin to be stapled onto the product.
AFAIK, country of origin labels aren't required in the EU, although there are efforts to change that.
I'd argue that the US got the better end of the value chain in this. Of course, it's possible for a company to outsource themselves out of business (cf Dell, which came quite close), but Apple does not seem to be on that trajectory.
(Apple isn't registered in Delaware.)
