Truth is they make it quite clear which nation in the first line of the article - I think The Verge are a global news source [albeit, yes, with a USA focus] and that they're quite cognisant of that, given the rest of this article.
.us is the ccTLD for USA. .com is the defacto default for all types of entities from across the world. Verisign call .com "The Global Online Standard". Yes, USA broke the convention and structure to preference themselves - that seems to be a favorite passtime.
As I said, the story made it clear it was USA in the first line of the article proper - I'd think that was part of The Verge being cognisant of the web being global and knowing that they get non-USA readers.
Personally I consider it foolish to assume web visitors are from a specific geography and that - in particular - a .com website is only to be read from, or at least in the context of, USA. There is no default country on the web IMO.
Starbucks is in Russia too.
