As for the notion (suggested by the passenger) that the offloading was due to him making a complaint, I expect that he would have an extraordinarily difficult time making a credible case.
Yes and in this case the conditions of carriage are key -
7a9) If you have used threatening, abusive or insulting words towards our ground staff or another passenger or a member of the crew of the aircraft.
7a10) If you have behaved in a threatening, abusive, insulting or disorderly way towards a member of our ground staff or a member of the crew of the aircraft.
There do not appear to be any exceptions to this, so it would seem that legally, he doesn't have a leg to stand on.
