Okay, apparently this isn't common knowledge.
He didn't know he was live. All player cams of a team are visible by the teams coaches and "dugout." They were joking with him when he got on and he flipped them the bird jokingly-- he had no idea his camera was live for the stream.
This fine and post is stupid. He's human, this was unintentional and this isn't what it seems.
Nah just gotta say his fine is bullshit. The dude made a rude gesture. So fucking what. It wasn’t directed at fans or a rival team member. It was a joke. Fuckin snowflakes.
People complaining about the fines are the reason overwatch isn’t esports ready if you can’t handle not acting stupid on stage then you shouldn’t be playing professionally instead go stream
