Larva surely went a bit overboard with his bm i would agree with that. The problem i have is that zotac didn't do anything about it in the moment, it would have been easy to just pause the game and tell him to stop.
No they apparently were fine with larva's action until all the offended people in the world went onto the internet and started crying. Instant reaction after that. That's really bad in my eyes, i don't want to see people operating that way :/
So yes Larva was disrespectful, i still enjoyed it though. People like to get mad and organisations actually act on this outrage. That's the actual horrible thing here.
