>why would anyone "donate" these is a different matter
This is a very big question though. WTF are people thinking? There's a difference between no longer wearing something because it no longer fits but is otherwise in good condition to not being used because it's completely ruined. What mental block exists in the original owner from just throwing away the ruined items vs just holding onto them to donate so someone else can throw it away? Do they actually feel like some good is coming from donating worthless items? I honestly just do understand this.
