My mum uses a 2014 ipad air 2 and it still works perfectly fine and even still receives security updates. I don't think Apple needs you to be buying a new ipad every few years. Every time the device needs replacing, its a chance you might switch to Android and stop paying for their subscriptions and 30% cut. The iPad is just one piece of the complete ecosystem. If they last forever without feeling obsolete, it builds a stronger brand.
