If this is a screenshot from a televised event (idk anything about it so idk if it is) it may have been done as processing for TV. They do it in the NHL with TV airings. They’ll cover the ads on the side of the arena with other ads more relevant to viewers not near the arena.
For example if Pittsburgh plays Edmonton at Edmonton. Edmonton has a bunch of ads for businesses in the Edmonton area but not Pittsburgh. So on TV they’ll digitally cover them with another ad that is either something nationally acceptable or local to Pittsburgh.
