Even though Embiid is loyal to this franchise, to Philadelphia, and to his teammates, he's not naive. He's not blind to the situation. There are certain expectations and standards that must be met in order for him to stay attached.
The Sixers' stance on Maxey has been remarkably consistent throughout the offseason - they view him as a cornerstone of their future. They don't just talk about building around Embiid; they talk about building around both him and Maxey. Any ear that will listen knows that the Sixers view Maxey as untouchable in trade talks.
But, Paul is obviously watching the Harden situation unfold from afar.
It wasn't all that long ago that he posted two sentences on his Instagram Story: "Been comfortable for so long. It's time to get uncomfortable." Now, Harden is trying to make the Sixers uncomfortable by opening the door to what he feels is the truth.
