Why does iTunes censor adult material?

I got into Breaking Bad a couple of weeks ago. I'd just finished The Walking Dead and needed something to fill the void. I loved Breaking Bad. The writing, the characters, and the plot was all truly excellent. I watched it on iTunes because we do not have Foxtell and regular TV does not offer dark, well written dramas. Everything on free-to-air has to be family friendly. There is never anything good on early in the night. It's nothing but reality TV. Stupid, boring, reality TV. The Voice. Celebrity Splash. My Kitchen Rules. Master Chef. The Biggest Loser. My husband and I are so sick of reality TV. There really is nothing else on. These shows are terrible. We hate how they try desperately to make things suspenseful. The shows are clearly scripted and people clearly are paid to pay a part in them. The people are actors. They have to be. At least in most of the shows. My Kitchen Rules is very fake.

To watch anything good you have to stay up until at least 9.30pm or 10.00pm. That's when things like Family Guy and the Cleveland Show and Nurse Jackie might be on. Because these shows air so late we miss most of them. I don't know if Breaking Bad aired on free-to-air. It might have...but we did not see it.

This is where iTunes comes in. It's a great way for us to catch up on awesome TV shows that never got shown a decent time on free-to-air or even at all. What's annoying about iTunes is how conservative it is. Breaking Bad is clearly for adults. It's about a man who starts making meth to provide for his family. And yet iTunes blurred out a naked woman's breasts and in another scene blurred out the letters UC in Fuck.

Firstly...why just the letters UC?

Secondly...why are they censoring women's breasts and the word fuck in a show that shows lots and lots of death and its central theme is the production of meth?

This is a show for adults. I can understand censoring a show that a child might watch - like the Simpsons. But this is Breaking Bad. Why shield adults from boobs and swear words? What are they doing? What makes those things so shameful but the killing of children is okay?

It really annoys me when iTunes does things like this. I am a grown adult. I have purchased a show for ADULTS. Please do not censor it. Or at least give me an option to purchase the non-censored version. Come to think of it why isn't there a non-censored version of TV shows and movies on iTunes? There are "clean" versions of music.
