Uh, I don't think this is really true.
Their repairability sucks for people wanting to do their own repairs, but Apple offers in-house repairs for devices up to 7 years old!
As for planned obsolescence, sure there is some involved, but Apple is by far ahead of the curve when it comes to balancing security and compatibility, at least in the smartphone world. Try finding a single Android phone that gets 7 years of OS updates and security support.
We can always demand better, but honestly they are so far ahead of the competition.
Besides, Apple has basically eliminated as much wasteful material as they can; compare recyclable aluminium to the plastic junk the PC world is using, not to mention the power-hungry Intel processors they use and their beefy power supplies.
People criticised the M1 iMac for being pointlessly thin, but it serves a major advantage by 1. reducing volume, and 3. recycling.
Yeah, but it's kind of ridiculous to demand a company to stop manufacturing entirely. Unless Apple found a way to make its business 99% services, keeping their hardware identical for years and only doing software enhancements, they cannot be net zero, sure. But even then, software is actually extremely harmful to the environment too, through the electricity usage of data centers.
