Things don’t really add up for me.

Yeh, I get ball tampering is bad. Cheating. Whatever.
Why is there so much outrage and the international governing body gives him a one match ban.
If it’s so damn serious, bam him for months, a year, a number of matches.

Also, the slippery slope of what you can get away with before it’s considered ball tampering.
You can polish one side of the ball til your heart is content using your trousers. Maybe ASICS could use a courser material for aerodynamics or sweat wicking. Throwing the ball over the pitch to scuff it.
