I know they could engineer a version of amigaOS so it would not run on certain hardware, but can they say older versions must not be used on these new compatibles?
IFAIK, In the USA they now can change their licensing for classic Amiga OS and stop people doing this in their own home with legally bought AmigaOS and minimig.
In the EU they could theoretically stop bundled sales but, unlike the USA, we can still fiddle and tinker with our own stuff in the comfort of our homes without being accused of being criminals. :-)
