Just to clarify. I'm not saying that Android is bad or that I hate it or whatever.
Android is nice and all, but there's enough advantages in Sailfish & Tizen to justify having them as alternate mobile platforms. One monolithic platform monopolizing almost 90% of the market is not healthy, open source or not. Especially, when most of that platform is dominated by one manufacturer (Samsung). So it's good to have alternates, especially when they allow benefits that Android doesn't.
