You are absolutely correct. The fact that this statement is made by a website holding itself out as an educational source is very disappointing.

Ultralight vehicles meeting these requirements (weight, single seater, etc.) are subject to NO airworthiness regulation by the FAA at all. So the FAA is making no statement on whether they are safe or easy to fly.

What these regulations mean is it is not a crime to fly something meeting these requirements (even if it was assembled by your crazy neighbor in their shed). That doesn't mean anyone would think it is a good idea, let alone the FAA.
