Not necessarily. When Jenee left, Eddie basically said "You know her mom decided there things she didn't like, so Jenee was pulled..." not direct quote, but the jist of it. He never went into detail, she wasn't really bashed in the episode (only on twitter), and that was that. Gabi leaves, and we all know it was for her family, but coaches took the same approach only adding, "You know she's still a kid," justifying her decision to leave. Again, no bashing...I'm not even sure she got anything hateful on twitter.
Tyler comes around and it's "Well, I didn't think he's make it anyway," and he left because he missed home.
Dylan leaves and it's "OMG how could he! He is the awful, devil, horrible person....ahhhhhhhhh".
With Tyler it could have just been, "He decided he wanted to go back home and cheer there, he was homesick."
Dylan could have been, "He decided this wasn't the right program fit for him, and he's no longer on the team. Now let me introduce you to Jacob."
Still a 'no comment' approach without the hateful bashing of a teenage boy.
