Hardware

I think I see where you're coming from, but a few points don't stick. I think ease of repair, availability of replacement parts and software support are often used in combination to dissuade the continued use of a product. I ended up ditching my (at the time new) Samsung S8 because it was so difficult to repair, well before it's scheduled end-of-life. It had a case, but shit happens.

And I think the more recent Iphones do actually block certain functionality if a part is replaced by a 3rd party, genuine article nonwithstanding. Having the part identified as genuine, 3rd party or non Apple installed in the settings or something would probably be fine, but that's not what's happening.

And for the last point, mostly agreed, but a business profiting from a customer's desire to do good doesn't disqualify the good that a business might do while also profiting. It would be great if there was some not-for-profit/governent run rating on device longevity/repairability, as some countries do for electricity/water useage, but I'll take the imperfect solution until then.
