Your American bias is just shining through, where of course you're not surprised.
Those both mean the exact same thing in this context. Genuinely interesting that you're not the only person who understood it a different way and suggested "default" instead. Neither would stand up to such pedantic scrutiny if you want to argue that one of them is wrong.
In such a short sentence about a topic that everyone here surely knows about, the words only reference the relevant aspect of the underlying information. You can't know if they have the wrong or right view without more information.

It absolutely is a US tld, run by a US corporation.DNS was originally a DARPA project, and was implicitly US focused from the very beginning of the internet, because it was a US project. ".com" carries that legacy because it predates the concept of country-specific TLD's.
A similar idea exists in reddit: /r/news is very US-focused, even though it's not called "US news". Since Reddit is an American site with an (at least initially) predominantly American audience, it's not surprising at all that things are American-biased by default unless explicitly named accordingly.
If we were all using Minitel instead of The Internet, we would have similar bias where services would be biased towards France unless shown otherwise, because Minitel was a French technology.
The point is, it's not explicitly a problem that somebody puts up a website and it's US-centric. Nobody owes the world an international version of whatever project they want to make, and you don't need to get upset that they only bother to cater to a US audience.
