EU companies selling in the US have to follow US regulations, US companies selling in the EU have to follow EU regulations. And in both cases, only for activities in the respective market. For example Apple would be free to sell lightning port iPhones in the US and USB-C iPhones in the EU. Or don't make USB-C iPhones and not sell any iPhones in the EU, if they don't want to be "leeched". Same for Nvidia and this hypothetical regulation for swappable RAM (which is never going to happen because it isn't technically viable)
