It's still just your opinion, there are no demands in Jazz, that's my opinion.I think it’s quite clear from my examples. Music does have parameters of style and it demands that players stay largely within them. Straying too far is wrong.
If playing a style where parameters of style are either blurred, very wide or non-existent - then the player can be experimental if they so wish.
A real example of something he did that was so wrong would be helpful
