Some eSports tournaments are cancelled since travel ban is applied to avoid an increase of confirmed cases of COVID-19 like majors of Dota 2 and other world championship tournament.
In fact, most of the tournament is normal. E-sport has a big advantage now and it should be used. Why should the organizers be lost? What for ??
The manager of eSports events is also a job and needs to make it a successful tournaments/event and to excel until the end. Hence big events such as TI or Worlds are considered a loss if postponed.
I agree, but all of these positions, ecositions can be replaced on the Internet. Not counting the losses, the next years may be in the plus because you don't need to hire security guards, cashiers, casters, you don't need to rent the hall and the end of the end will pay off.
