The official Twitter apps for iPhone and iPad have now begun showing an option to show a translated version of tweets below the native-language version, using Microsoft’s Bing translation services. Similarly, the social service has expanded the ability to show tweet translations in the Twitter.com Web interface timeline as well.
So Twitter is using Microsofts Bing instead of Google, exactly as Apple is doing in iOS 8. Personally I believe Apple has a large hand over Twitter, I think they are part of the important decisions Twitter make. Apple Has integrated Twitter very deeply into both iOS and OS X. Twitter Is important for Apple. To me they could even buy them if they have to.
