I think it's pretty amazing you didn't see the two screws and think 'hey these are probably the same width as the braze-ons on bottle-cage equipped bike', so to then say 'hey - you mean it doesn't come with a cage?' is really due to a lack of observation on your part.
I'd imagine the idea of it being an 'adapter' is so you can fit your own choice of cage and bottle; if it came with a specific cage then you'd only be able to use one specific fit of bottle.
This way gives you the choice to fit any. ie it's a good thing, not - as reading your other recent posts I'm pretty much sure you assumed - some kind of way of ripping you off.
