This criticism seems fair of devices with consumable parts, like batteries. But of a charger? How can this be anything other than waste once it's no longer useful?

Exactly! Shameless plug: we do a repairable design for e-bike battery which uses no glue (https://gouach.com)

Really nice, and in the future those cells could be upcycled or repaired. The design is also quite dense.

To be clear, I have designed high-density electronics myself which were repairable - it's tough but doable.

Exactly! It's known that recycling pristine cells that haven't been glued/welded etc makes it much easier and efficient to recover lithium, so that's also a win for recycling

Not bad, I thought the folding prongs on this Apple adapter made it a fairly shameless plug itself :)

haha :)
