If you say 2. is clearly wrong, what are your numbers specifically that disagree with the research summarised in the "Impact" section? Or do you disagree with some part of the linked study? (Which does already take the forced replacement into account)
Yes, of course I disagree with these numbers. First, the study says it doesn't take into account the impact of wireless charging. Well, all I do is wireless charging these days, so already the study is worthless in that respect. Furthermore, a lot of benefits it attributes to unbundling, which Apple already also does for quite a while. Finally, these are made up make-belief numbers without any solid backing, given that all these factors are not really included. Personally, I didn't need another cable for the last 5 years, and I am a heavy Apple user. Somebody else was complaining that they need another cable between their switch, laptop, and iPhone. Yes, the cable is what makes the environmental difference here. Ridiculous.
