In my case, Google always shows sites located in Russia first (first 10 results are always in .ru), despite that I located in Ukraine, and write queries in Ukrainian language, even lang:uk does not help, so I must restrict results with site:ua. IMHO, Google just sold places on their first page, so Google is not screwed and will never be.
