In all honesty, Cloanto bought the Amiga brand. Anything they have done with it has been minimal. They have to make some money back off of their investment, this is called business!
Would you buy something for a few million to just sit there and do not very much - better still give it away free? No, course not.
But that said, even if they sold a billion copies of AF, I doubt they would ever do anything constructive with the technology.
