Why? They operate via multiple subsidiaries (the EU one is registered in Eindhoven), most notably Singapore and Taiwan, and do their main manufacturing in Taiwan.

Many US companies operate via subsidiaries and manufacture their products in Asia. But that doesn’t matter if the main business is based in the US. The current US government, its seemingly random tariffs, and their plans to cut their country off the rest of the world make it hard for me to invest my money and energy into products from the US if I’m not sure if in a year from now I still will get support for them as a customer from Europe.
