Yes, they've been litigious
Could anybody make a list of a the litigations in Amiga history and count how many each of the companies have started. I think you would be amazed.
The only thing I see is some quote from Ben Hermans in a heated discussion with BB & co. and a declaration during a trial. Don't know if people here read groklaw but during declaratory phase (if that is the right name) you are forced to declare all things that you possibly want to bring forward during the procedure. You are not allowed to bring new things on the table during the rest of the trial. So common practice is to put everything on paper in some conditional way (probably ilegal) at the start even if still need to investigate further if it really is the case.
