vSAN: No witness! No problem?

When you study how vSAN works then you will read about how objects are backed by one or more components. This is dependent on the fault tolerance level and what you would also read is that a tie-breaker witness will be created. This is to make sure that when a network partition occurs, servers in a network partition can decide whether or not they together hold more than 50% of the necessary components and/or witnesses.
