From the battle footage, the damage done to Storm 2 looked to be sustained from Matilda's flywheel rather than Typhoon 2, but it was still damage to Storm 2. Could be classed as poor control from them, pushing a robot into a danger zone without ensuring they are able to retreat undamaged. As for the other incidents, I am aware of them and have read accounts supporting or disagreeing with them but to be honest, I think it is all immaterial as:
a) it's been over 7 years since these events took place,
b) the result stills stands regardless of how much injustice is perceived to be done, and
c)Mentorn is a TV company who were always more interested in getting a good-looking spectacle than being fair, so it's no surprise that such decisions were made.
