Not for the first time mr Anderson has been caught ball tampering on tv. He's got away with it a few times in the past as I recall. Im sure if a pakistan bowler had done it he would've been blasted for it and banned.
He was removing something from the shiny sides seam, something most of us do on a weekly basis when grass/dirt gets caught in it.
England were tampering with the ball by throwing it in on the bounce as much as possible, something the Ozzies also did all day.
It's part of the game, every team does it to get a ball to reverse, and if they don't... more fool them!
Move on!
