Good question, though this was my first comment in the chain, I personally wasn’t complaining (yet).
To be honest, I’ve just checked the “Top Day” sorting of /c/[email protected], and the news are all about non-USA topics. So in hindsight I guess OP was just doing the usual “lol self-centred Americans” dunking. It is a fact that American news have pushed out the other countries’ news from the default news sub on reddit and here (or more likely the system was just replicated on Lemmy by default during the migration), so it’s a sort of folklore reaction… :D
