I saw a lot of people having fun and didn't see people getting really angry. Though I'm sure there were people actually getting angry, that happens with every game. Maybe those people should relax more, but ¯\_(ツ)_/¯. I was part of a community maintaining a small logo that got attacked a few times, and we repaired it - part of the fun. I agree with the people who think a canvas full of flags is kind of boring and wish people didn't jump so quickly into nationalistic identities as a way to express themselves, but ¯\_(ツ)_/¯.
