their primary relation with the CBM/Amiga community has been sending over a PR rep whose main activity was insulting anybody with the temerity to suggest that maybe we'd be interested in something that wasn't PC clone hardware in a novelty case
Except that never happened. Nobody from CUSA, as far as I have ever seen has even implied that you shouldn't be interested in pure retro. It is the pure retro group that attacked CUSA saying that they should not exist. It is not CUSA that has claimed both cannot exist. It is the 'pure' retro trolls that have done that.
