Product manufacturers seem to be using AI increasingly, and many sellers feel they should include it because it's words by the manufacturer and, worse, totally replace the seller's own more useful words such as the condition of a 'used' item, size/dimensions, or, in the category I mainly shop in, "needs an A4 die cutting machine" (not everyone has one), "ideal for making [certain format] cards", "comes with artwork - download it free from the manufacturer's website".

Perhaps such sellers feel whatever a manufacturer writes, no matter how inane or uninformative, is more important than what they would write? so that, apart from that, the listing's Description is empty (apart from, say, "comes from a smoke-free home" or "I combine postage").
