Refresh cadence has little to do with sustainability.
Consider cars: manufactures come out with new ones each year with marginally differences. Is that somehow unsustainable and they should instead keep manufacturing an old design for years? Does that mean once the 2026 model starts manufactuing you go dump your 2025?
It makes more sense to iteratively improve your design and stop manufacturing old things if you can manufacture something better.
The real sustainability argument is about support length (which apple does well), and repairability (which apples does ). Changing to a 3 hear cycle is orthogonal to both of these.
