This is really misinformed. Apple has a VP position for environment which is staffed by former head of the EPA Lisa Jackson. At the last keynote event she got a prime time on stage to talk about Apple’s major initiative to make their devices last longer. IOS 12 is running on the 5S, which is a 6 year old phones, and not only that but a major focus for this version was to improve performance on older devices. I use a 5S for travel and as a test device and it is still perfectly usable, maybe more so than ever.

There is no other manufacturer of computer equipment that comes close to maintaining service and usability on older devices than Apple at this point, and this has been shown over and over again by the resale value that their older devices still command. Many Android phones, even Nexus and Pixel devices only received updates for 1.5-2 years after their last sell date.

You’ll find very few companies that focus as much on environmental impact, and Apple recycles any product they have ever manufactured at their own expense. See here: https://www.apple.com/ca/environment/
