I've never understood why Android users expect their operating system to be updated. Nobody promised us that the OS would be updated on a particular schedule, or even updated at all. The idea that a company "owes" us updates strikes me as just ridiculous.
That is the most absurd thing I have read yet.
You don't buy an operating system like Windows and expect it not to receive updates. The reason being is that BETA testing cannot find every bug. Thus the software goes out to the masses and receives updates as and when 'real world' usage discovers them.
The exact same applies to mobile OS's. Even more so in today's technological age where our mobile phones really are, computers in our pockets. Even back in the early days of smart phones Nokia would push out downlandable software updates and later OTA. No they didn't promise them at point of sale, but they didn't need to, because they were a decent company that ensured it's existing customer base received updates to iron out bugs and improve the customer's experience.
So yes, when I buy a mobile phone now, especially if it's running some form of one of the big three systems, I expect it to be updated, to a finite extent.
Also, it's very naive to have the closed view that just because your device is not experiencing a particular bug, then others should put up and shut up.
