Sorry for following one of Franko's posts yet again, I don't want it look like we're becoming a double act, lol. ;-)
The way I read it is that Cloanto have a license to distribute WorkBench for use in emulation, but not for use on real Amiga hardware.
I'm no lawyer, but it seems to me that if they don't have the right to distribute original WorkBench discs, then they don't have a mandate to prevent anyone else from doing so - It would be no different to ME telling Franko to stop doing it.
As desiv says, it looks very much like they are overstepping their license by filing a takedown claim against Franko - Only the true copyright holders can do that, I believe.
This raises further questions, because users of genuine Amiga hardware must surely have a right to possess the software that was originally supplied with the machine & which is vital to the machine's operation ? Are the copyright holders obliged to make the discs available at a reasonable cost ? Are they interested ? (I think we all know the answer to that one, lol ;-)
