I could count two non US/UK green sources. If that's the outlook they have, Wikipedia should have no business documenting anything outside the Anglosphere.
I count eight of them. I'm not sure which six you ignored, but there's three of them before you live the 'A's.
The bias you're seeing towards the lack of non-Anglosphere sources in the list is likely the bias against non-English sources--whether good or bad. There's not a lot of French newspapers in that list, for example.
This list is essentially culled from discussions of "is this source reliable or not?" on the English-language discussions in Wikipedia. Non-English-language sources simply aren't going to appear in those discussions with any frequency, because most editors editing English-language articles aren't going to be using non-English-language sources.
