The outrage at not being able to repair a 4gm Airpod when compared to the complete disregard to wasting other resources, in my opinion, has a very dubious moral stance.
I get that the price paid is indicative of the engineering that went into the product and you feel it might be outrageous to pay that amount for 2x 4gm.
Any argument about repairability needs to be considered in the context of actual resources used to make the product, what the cost to humanity was when compared to what it will cost to repair the product, including the human cost.
The same way that many good wired headphones allow you to replace the cables and earpads. That makes them last for decades as long as spare parts are available.
Now with wireless headphones when the battery dies you're SOL. You better pony up for a new pair even though the failed part costs ~$5 and could be replaced easily with good design and part availability.
