No, but at some point everything has to be discontinued. You can't reasonably expect manufacturers to continue to support their products indefinitely, particularly without recompense. To put it another way; are you willing to either pay more up front or some kind of ongoing fee in order to fund the manufacturer continuing to produce software updates for a device which is multiple years and multiple generations out of date? > > Which is the point.

Even the last service pack was released in April 2008. That's a pretty long life and I don't think it would be reasonable to expect Microsoft to continue to spend time and money supporting it any further. Users need to take some responsibility when it comes to making sure that their software (or firmware in the case of embedded devices) is still supported by the manufacturer. If you choose to use it past the end of the manufacturer's support, then you need to be prepared for the potential consequences of doing so, including that your service provider disconnects you from their network as your device(s) are participating in DoS attacks. Of course, the manufacturer needs to provide the user with some kind of reasonable expectation of the lifetime of a device so that they can make the appropriate plans to invest in a suitable replacement. In the case of Windows XP there has been a published official lifecycle for an extremely long time (since SP3 was released?). There was also a lot of press coverage before and after the end of support, so it shouldn't exactly come as a surprise to anyone. For the iPhone, new versions of iOS generally support the last 4-5 iterations of the hardware (I'm not sure if there is an official published policy about this), which is typically updated annually. Currently that is the iPhone 5/5C from September 2012, the iPhone 5S from September 2013, the iPhone 6/6+ from September 2014, the iPhone 6S/6S+/SE from September 2015 and the iPhone 7/7+ from September 2016.
