When comparing, please keep in mind that the ultra-mobile (i.e. tablet) market as well as iOS are barely in their infancy, when compared to evolved products like stereo components or TV sets (and even PC's and Laptops, for that matter).
Old TV sets could only be used for decades because there had been no relevant technical progress for decades. Old tube TV's can not (properly) display HD ready programs, let alone FullHD. And their practical size for home use was at the limit with ~32".
Same goes for older computers: Performancewise, technology plateaued several years ago for "standard" tasks like office (and to a certain extent web browsing), so it's easy to run newer OS's on older machines. But there has been a time where you had to upgrade your computer hardware nearly on a yearly basis to keep up with software development.
Same is now going on with mobile devices like tablets and smartphones: Software progress is so fast that hardware components struggle to keep up. How someone can make up a conspiracy theory from the fact that a 6 year old device in the ultra-mobile market is technically unable to meet current software requirements is beyond me ...
