That's your opinion. Down is soft, supportive, and breathable. Great qualities for pillows. You're strawmanning again with the chickpeas.

It does, it wicks moisture through filaments and is highly breathable. It regulates the body temperature of geese, it's job is thermoregulation.

Edit: in case anyone gets this far, I highly doubt it, but I had to block that guy because he's made of nonsense.

Geese molt down several times a year, but they always have down, they molt their flight feathers in summer and can't fly for a few months. Down is there for thermoregulation.

"Geese are warm blooded and their temperature must be regulated within a certain limit. This is only possible when enough wind reaches their skin to take away the heat. The down protects the birds from the cold during the winters and keeps the bird well aerated, so that its body temperature is also optimally regulated during the summers."
