I think it's like the pass interference penalties in football--they give a huge unfair advantage to the offense if they can induce the defense to do something illegal.

All you have to do, in football, is to induce the defender to contact you/interfere with the play while the ball is in the air and you're way down the field, such that the ball is catchable and isn't caught, and you're that much farther towards your offensive destination. It's a legal strategy to do that, AFAIK, but it's very difficult to implement effectively and repeatedly.

The difference here is that some teams figured out a way to do it every time they "call a pass play", and use that as a primary strategy.

As soon as some NFL team figures out how to use it as a primary strategy, I bet that somebody will be complaining using the exact same argument used here--and that it'll be changed for the next NFL season.
