Why does the NFL discourage end zone celebrations?

Of course, the crackdown on “celebrations” can be “quite ridiculous” (not NFL, but still ridiculous)

My post from the other celebration thread referencing the same incident.

Celebrating before the line is taunting. There were several defensive players nearby and it was clearly an “in your face, I beat you” gesture. The kid just learned a valuable lesson.
