Many things are called different things in different places. I grow chestnuts and most people in the USA refer to them as a "nut". Nothing in the names of them in other countries gives them any association with other nuts. They are a high moisture fruit that is similar to an acorn (but tastier!). Further, in the UK the term "chestnut" is usually a reference to the horse chestnut, completely unrelated, while they call a chestnut a "sweet chestnut". It can get quite confusing. I suggest not reading too much into why someone is using particular terms in a language that is not native to them. Now for someone that still sells "Ae Ae seeds" on eBay, that's definitely a scam!
