Okay that explains it. I thought banning for 12 months was a little harsh for someone making a political statement once, but he knew what he was doing and doubled down on it.
For example, I have a first amendment right to stand on the street and cry out "that store over there has awful working conditions," and I'm not breaking any rules, but I'm well aware that the store may well not let me in anymore.
If the rules are ridiculous, then the reaction to them should be to dismantle the rules and disavow the rule-makers.
I support non-disruptive actions like kneeling at an anthem, but advocacy about a political issue during a post-match interview streamed by the event organizer certainly crosses the line.
