The topic is not about Betnomi though. It's about who offer VAR.
I did not have any idea that VAR could be a good betting market too. In fact, card market, foul market (hope it exists too) are also easy to manipulate. The referee team team can have a good contact with a gambling agent and manipulate it easily. The results of these kind of event does not make much change in the match (Not all the time)
