Speaking for myself, if you've ever had your three year old yell something like
"Okay Daddy, let's play some f***ing music!!" in front of the extended family because he walked up on you one single time three months earlier as you were watching a youtube video on speakers of some band in the recording studio, it kind of opens your eyes as to why people might want to know when to expect profanity and be able to shut it off if necessary. Kids pick up all the wrong things.

Since I'm the music guy in the family it was pretty obvious he didn't get it from c'beebies...
