> So the Belgians enshittified speculaas to create speculoos

Yes and no. This "Speculoos is actually cheap Speculaas" isn't completely true. That's what people like to say today, but the "Speculoos" name has been around much longer than Lotus bakeries. It's just a dialect thing and there is no reason. Some people called it "Speculaas", some people called it "Speculoos", and _then_ a cheaper variant got made and they choose the "Speculoos" term for it.

It all just sounds really fitting because the "-loos" suffix in Dutch means "without".
