i don't understand why people don't understand what android's software releases by google are: they're *example* source code which is neither the legal nor the actual responsibility of google to install or manage. google does not own asus: it is a separate company. google does not own samsung: it is a separate company google does not own any of the china ODMs or Fabless Semiconductor Companies: they are all entirely separate companies.
so to make *any* kind of suggestion that google should do this or should do that - should make OS updates, should make automatic OS updates, should take responsibility for another company's decisions - it's all absolute total nonsense.
the only products that google is actually legally responsible for is the products that google themselves sell. the nexus range. THAT'S IT. (and even there, even google are screwing up: automatic updates have resulted in people's devices being bricked). ironic isn't it: google provides the nexus, as a leading demonstration to other 3rd party companies.... yet not even they can get it right.
so partly in recognition of this problem, google bought motorola, as a bigger "attention grabber" and a bigger leading demonstration to other 3rd parties of how to get this right: how to create products that use android.
now, the thing is, lucian - the thing that you haven't mentioned - is that all these companies using android - they're all profit-maximising corporations. those automatic software updates you believe they should deploy? that requires that those companies - all of them - spend money. that eats at profits, which are amazingly slim.
so i ask you: what justification, then, is there, for these companies to reduce their profits, *especially* when any "support" for older products - which you would *continue* to use if there were "OS Updates" available! - is *also* a reduction of profits?
why would *any* pathological profit-maximising corporation even *remotely* consider - for one second - the anathemic concept of extending the lifetime of unprofitable older products??
are you starting to get it now??
the laws that forcibly require company directors to enact the articles of incorporation that include profit-maximisation clauses *DIRECTLY* result in the endless cycle of design, sell, abandon, design, sell, abandon.
now, we can see that this is incredibly irresponsible, but there really is absolutely nothing that any of these profit-maximising corporations can do. they're quite literally stuck in the pattern that results from the setup - predictably, too.
how can this pattern be broken? well, the key is that the design of these products ties the SoC (the system-on-a-chip - the main processor) to the Operating System. each firmware release is absolutely and intimately bound to the processor, and once a product is sold with that processor (and operating system) the *entire* product - SoC, OS, firmware - is forgotten about by the manufacturer (to the maximum extent that is permitted by law that does not interfere with profit maximisation).
so surely, then, the solution would be to design products where the *entire computer* - including the OS and firmware - is removable and upgradeable.
this is what i am designing - at http://rhombus-tech.net. modular upgradeable products. the concept you will be familiar with from phonebloks.com, except that phonebloks is an advocacy platform that started a couple of years ago, and i've been working patiently on creating *actual* real-world products for the past five years.
unfortunately, modular product designs are not profit maximising designs when monolithic designs are the "norm". so this paradigm shift is something that, *at the moment*, no profit maximising corporation that creates *existing* tablets and smartphones is *ever* going to be interested in... until such modular upgradeable products have also become the "norm", at which point they will see the benefits and profit opportunities (and happier customers) and will start to commit resources.
but to get over that hurdle, you're going to need to support efforts like mine that pave the way. if you or anyone else would like to do that, here are a couple of links:
