The terms of service update to clarify what we have always done, comply with relevant law, has not changed the situation for either country.
According to https://news.ycombinator.com/item?id=48457280 it affects all people ordinarily resident in those territories, not just their governments:
> You are not a person or entity that is:
> (a) located in, organized under the laws of, or ordinarily resident in any country or territory that is the target of comprehensive U.S. sanctions;
> [other 'or' conditions]
you may legally own a house in both X and Y, but if you spend 90% of your time at X, you are "ordinarily resident" in that jurisdiction (X), and you would not be ordinarily resident in jurisdiction Y.
"You are not a person or entity that is: (a) located in, organized under the laws of, or ordinarily resident in any country or territory that is the target of comprehensive U.S. sanctions; "
this says nothing (edit: specific) about government (edit: only), and is applicable to normal people in those areas.
Still needs updating if it's supposed to only apply to governments, though.
