Up until very recently, only Apple had over 5 years of software support on their phones. With others you'd be lucky to get 3 on flagships and yet Apple had 6-7 years on some models. You could use your phone for 3 years, pass it on to a family member and they'd get to use it for another few years, while still getting updates. I'd argue that if you had a Samsung, you would've needed to update more often.

On the computer side they unfortunately do force regular users to upgrade after 6-7 years, which for that market is significantly less than anything running Linux. Of course if you know how to google it, you can get new OS updates for more like 10 if not 15 years. Still scummy. But nobody replaces them annually. Companies replace laptops at 3-4 years usually.
