So why the change?

In an older blog entry, dated April 19, about Al Sobotka's banning, Tony Hagen questions why the changes from the NHL's stance from last year.

My question still remains, who complained? Why now? What prompted this rule to be issued? Is $ 10,000 really necessary?

Those are very good questions that need to be answered honestly and without Gary Bettman spin.
I posed a similar question too in my first blog about this octopi-matter.
The change seems rather arbitrary to me. There was probably little or no research done either.
