You're purposely choosing to highlight the extreme cases as a defence to Ten Hag's man management. They have chosen (incorrectly) to react to however they've been treated by Ten Hag in an extreme way. That's down to them and their personalities, not everyone makes the right choices.
Lets broaden the picture though, people you're forgetting to mention: Maguire, De Gea, McTomminay, Varane, Martial, Wan Bissaka, Bailley, Fred.
All these players have been dropped or targeted by the manager at some point during their time at United. Some spoke to the press while on international duty, some just shut up and got on with it and left in the end when they could, De Gea just left instead of signing a lesser contract and playing under Ten Hag again.
Before you make this out as me defending the players, I'm not. A lot of them either aren't good enough for United or didn't deserve to play anyway, which means they were in a position of weakness from the start so they couldn't complain like Sancho, Rashford or Ronaldo, because literally no one will take them anyway. They still deserve to be treated with respect however, otherwise the guys that you are playing and are relying on will turn on you at some point also, because they know one day they'll fall into that category.
