I think you are thinking about this wrong, if you look at this device, it's a hardware emulator, a totally new device in an "FPGA" all in one chip. It's not an "Amiga" and though it can do a lot of the same things and run a lot of the same code.. If you looked at the three custom chips and the circuits I am sure you'd find them not really the same thing..
The important thing about this is that it isn't a "copy" of someone else's property. It solves a problem for you but it doesn't have the name "Amiga". It's a "minimig" and it just happens to be able to do most things the A1000 could do.
Why could A-inc hold it up anyway, as far as I have seen it doesn't violate any of their hardware designs or rights technically and not using any intellectual property. It's like a modern "clean room clone"..
I don't think we should be calling it Amiga, but it's name "Minimig". I don't think as a community we should call it an "Amiga" because that's giving a tip of the hat to a company that if they had anything to do with it's development we would have never see it come out..
