> Maybe they will move all their devices to their own superior OS Tizen. Or maybe they tried and it did not turn out very well.
Google (via the Open Handset Alliance) managed to enforce the current status quo. Manufacturers can't simultaneously ship their own OS like forked versions of Android, or presumably Tizen, and still be allowed to use Google Play Services. It's all-Google or nothing. I don't know whether Tizen is superior or not but one could assume it isn't simply due to the lacking ecosystem. Windows Phone was a good OS. It was shot in the foot by a weak app ecosystem.
> So whichever side Samsung is it does not affect Google.
Samsung has 20% of the market and a lot more of the high end market. Going with "not Google" means a lot of users no longer using Google Play Store and services. It most certainly would "affect" Google.
