Many people are angry at Novak Djokovic. And its sponsors can just wait for it. It is unclear whether the No. 1 seed can compete at the Australian Open on Monday after Australian authorities revoked his visa due to the lack of a COVID19 vaccine. So far, sponsors such as French automaker Peugeot, clothing brand Lacoste and Swiss watchmaker Hublot do not plan to drop him. Djokovic has brutal moments like breaking his racket, which may be some brand gamble that’s a hit with fans. But there is a line. Experts say sponsors must determine whether an athlete has acted illegally or unethically if they want to contract bad behavior.
