People put up with it because they don't really know of any alternative outside iOS. And until recently, financed phones were pretty much only available through your carrier, firmly locking you into the carrier channel and everything that entails. People might not like the nonsense--to the extent that they even think about it (honestly, Android updates take so long I know people who don't even realize that major updates are even an option for them)--but they dislike it a whole lot less than the idea of spending two grand in cash and all at once to outfit a family of four with new phones.
