So how would this work, the Chinese ISP is inspecting unencrypted packets from videogames for banned text and shutting down the connection on seeing any? Wouldn't most relevant text be on https websites anyway, why even implement something that way when the text isn't guaranteed to be in a clear standard format and it's just game chats?
They never saw the message, they saw anon disconnecting, anon saw them disconnecting. Behind the scenes Blizzard made them shadow-ban each other, they will never share the same server shard again. Both sides think they won and Blizzard will continue taking money from both. /conspiracy
