As the lead referee for this event, let me respond.
We keep a constant watch on all the players on stage at all times. We have cameras as well as live people walking onto stage to keep tabs in everything. All players are told that they need to remain sitting, facing forward, and with headphones on at all times, including during pauses. I can personally confirm that no WE player looked at the minimap at any point during the match.
Players make eye contact on stage fairly regularly. Team WE in particular talked directly to each other a good amount. A single, limited camera view with a field of a few feet is not enough to determine where a someone is looking on a cross-stage scale. We directly monitor players to assure this is not the case, and maintained due diligence at all times over the course of the event.
Say what you like about WE's gameplay, but they did not jeopardize their chances of staying in the tournament by looking at the minimap (EDIT for clarity- because they didn't look at the minimap. If they had looked at the minimap, it would have jeopardized their standing in the tournament. I am not, in any way, condoning any player who gains an unfair advantage from any means).
