Well, if that were the case then it would be illegal for any player to enter into a contract to sponsor a product without getting prior consent from the NFL. So either the NFL or the individual players are in breach of the contract with Beats. Ultimately, this will be decided in a court of law and either the NFL or the players themselves will have to recompense Apple.
What are you talking about? There are no lawsuits happening here. Players are allowed to sponsor products as individuals. But they can't sponsor products with the endorsement of their team or the NFL with the NFL's consent. No one is in breach of anything. I think you are reading way too much into this.
Again this is nothing new. Plenty of players are sponsored by other sports drink manufacturers besides Gatorade. But they will not be shown drinking from anything but a gatorade cup or bottle during the game or press conferences.
