Ask HN: If a country gets on the bad side of US, what all tech it can lose?

With the recent Russia-Ukraine war got me thinking how many of these global companies are American first when appropriate time. The stakes were high this time but the boycott could be used as a tool in future for much lower stakes.

Is there a protection against it in other countries? Will AWS, Teams, Google, PayPal, Twitter stop working? What other critical services run by American corp can be at risk?
