It's sport, shit happens. Yeah Conte would scare the players enough to not get a response like that. There are different ways to manage players, none of them are flawless.
Look at Fergie with his (more serious) issues with players such as Beckham and Stam. He cut off his nose to spite his face and made United weaker at least for the short term. The authoritarian approach works if you have players willing to be manipulated, it's easy to hold together in the short term with an almost siege mentality, Juve these days are absolute favourites in almost all games, that's difficult to manage and keep players focused.
