I don't think AmigaOS name is toxic - far from it. Amiga and AmigaOS names still have value - a wider audience (not Amigans... not those who've lived through the nonsense) will remember the name fondly. That's something which can be capitalised on.
Which is why all parties who have any saying in the matter are spending their "fortunes" in court these days, fighting over the brand, copyrights, distribution rights, its trademarks etc. Or to sum it up in one word - toxic.
