It’s mostly knockoff products sold at way more than they should be with a fresh coat of paint. A raspberry pi 4 for example retails at ~$70. Take that same board and have it basically sold by the OEM, pretty much at cost, but advertise it as a fake “Switch” and sell it for $100. They also get rid of plenty of dead or manufactured overstock.
Maybe a dev just right click propertied their folder and typed that in haha. I think it’s probably downloaded and cached community content. Unless it’s a hint at new danger zone stuff
