What you’re missing, and I’ll paraphrase here, is that someone that doesn’t want to recycle is going to toss their device in the landfill, regardless of how many slots are in it, regardless of whether or not it has resale value, regardless of how many people they know could use a computer, etc. No one is going to change their minds and, really, they’re free to do what they want with the stuff they don’t want to use anymore.What you're missing is that a Mac that can be easily upgraded has resale value
To expect that Apple or anyone else can, with the wave of a wand, force everyone using Apple devices to be more responsible with their unused items is not realistic.
