#Google its time to start requiring OEMS to start loading phones with vanilla android and to put their skins on their phones as downloadable launchers. 5.0 hasn't reached my #Samsung Note 4 as of yet and at this pint I don't care. KitKat 4.4.2 - 4.4.4 were a joke of a software updates that cost me a Galaxy S5 because it used up all of my RAM causing my former phone to randomly reboot or freeze up. This resulted in me having to go to my carrier trade in my S5 and buy the Note 4.
No, it isn't, Android is a Linix based FOSS, Google can not force anyone to do anything because they will just use outright forks if Google gets uppity, modified so as to not permit Google to spam or data mine their clients.
