In the US, if a player won the tournament and went political during the post match interview the likely response would be to switch to a commentator and that would be the end of it. Instead they went nuclear on him, banning him, clawing back winnings, going silent on the issue until finally responding on a Friday night.

There is a big difference between "not supporting" a political rant, which could be accomplished by turning off his mic and what Blizzard chose to do.
