Is Google really thinking Android as open source ?

This is the thought , for what most of the customers and people out there have sympathy for . For every upcoming OS , apps're a necessary thing , otherwise though OS is good , but it becomes boring as we spend time with it . While we know , Android is the most portable OS in the world , which can adjust itself to any environment , its advantages are uncountable . Like What Nokia did with X line  . That  undoubtedly proves that Android is Open - Source . Though this term is questioned sometimes by people  ,  like now Google is asking manufacturers to have Powered By Android branding during phone boot up  and Google removing Cyanogen Mod app from the Google Play Store . Well the answer given by Google wasn't practical at all - " THE APP WAS HELPING PEOPLE VIOLATE THE PLAY STORE POLICIES AND EVEN VIOLATE THEIR WARRANTY "

 

Also previously there were reports that Samsung may kill Magazine UX  , to promote Google Services as some kind of deal with between two . Also there are reports saying Samsung to completely be with Tizen , killing Android . But that strategy is confusing , because that's huge risk that  Samsung is taking on , as Samsung became famous due to Android , right ? The Cyanogen Mod app removal from Play Store was the first step of doubt , that whether Google is really thinking Android as open source . While third party devs , make the use of it's friendly environment to it's core .

 

While the Open Source word is truly confirmed by the JOLLA , Blackberry people . Their OS like Sailfish and BB10.2 .1  can run apks and you can side-load them to the device   , which is the same case with Nokia X line-up which is running on Android Open Source Project  .  While there were rumours about Windows Phone 8.1 may have apk support , but that may not be true at all or maybe , let's see .

 

All the above said facts , conclude that Google is considering Android to be Open Source , but at some points don't !
