If I avoid buying down-filled duvets, will I save geese from live-gathering of feathers?

Around 98% of down and feathers are obtained as a by-product after the birds have been slaughtered and thus will accrue regardless of whether there is a demand for bedding articles or not. Geese and ducks are being kept for the purpose of meat production. Down and feathers are just by-products.
