> Do vendors actually want to let users update the software on their devices though? Apple does because they can still generate revenue off old devices via AppStore sales and services. Also used / hand-me-down iPhones expand their user base by serving the low-end of the market. Android OEM's on the other hand get basically nothing from Google and don't want desirable used / hand-me-down devices devaluing their own low-end models. They can't even try to negotiate a more sustainable arrangement with Google because there's no viable alternatives to Android.
