I think it's all self inflicted by Dana. Using the bus incident to promote everything, allowing Conor to talk down on Khabib, his family and his belief's etc - it all came back to smack him in the face and tbh this may have damaged the UFC's brand. If the commission want to be dead set about this investigation, surely they will punish the root cause of what happened and that being Dana. Obviously he isn't responsible Khabib's actions, and Khabib should definitely deal with those consequences, but the way Dana has been running this the last few years is just terrible.
