So yeah, doing business in the US, getting paid by US people, subjects them to some US regulations. Hence, they are affected by US domestic policy and politics.

This is the point of this thread that you are arguing against by making up scenarios for the customer or Proton to avoid US entanglements. The point of this thread is that yes, Proton is subject to US law regarding money made in the US. End of story.

If you want to create hypotheticals where Proton excludes US customers or coulda done this and coulda done that, whatever man. You can make up whatever you want to be right. The question has been answered.
