An anonymous reader shares an update on Google's ongoing battle with Russian regulators: Google suffered a major blow in Russia on Monday, after the Moscow Arbitration court sided with an earlier ruling that Google had violated the country's anti-trust rules by having its apps and services bundled on Android smartphones. Yandex, a Russia-based search engine, last year sued Google over "anti-competitive practices," saying that Google was abusing its dominant position in the market to hurt competition. In response, Google had noted that Android, which roughly owns 80 percent of the market, is a free and open source operating system. At the time, the Russian Federal Anti-Monopoly Service (FAS) ruled that Android users must not be catered with Google's homegrown apps and services. The Moscow's Arbitration Court ruling said on Monday that it fully supports the earlier FAS decision. According to an Ars Technica report, "Google will now be required to change its business practices with smartphone makers in Russia, or else face a fine if it fails to adhere to the ruling."
