Rockersuke, Cloanto merely has a distribution license for the KS and WB.. They do not own it in any way.. It's still Amiga Inc's intellectual property and Cloanto can not do what they please with it.
A bit like your local store selling DVD movies.. They are allowed to retail the DVD but do not own the content that is pressed onto the discs..
Of course my analogy is not perfect - Cloanto has a license to manufacture and distribute the media containing the Amiga Inc IP, whereas your supermarket only gets to buy the product from somewhere and sell it for profit.
