I would be more concerned that Digiman could be considered an OEM making a computer with an "Amiga-like OS" myself, that could be an issue.
Is Digiman hired by or anyhow connected to Amiga Inc? Has I got a license from Amiga Inc? Is him going to sell Amiga branded computers?
The answer to all these questions is NO, so there is absolutely NO PROBLEM in being a OEM making a computer with an Amiga-like OS.
