Define "corporate America." The majority of American companies, even Disney, do whatever it takes to make money, including catering to sexual interests.
Apple is one of the few that has different standards. And some of its consumers appreciate that. There's room in the market for both views.
Almost nobody wants their advertisement running next to porn. Almost nobody permits their services to be used for sexual activity unless said service explicitly caters to it. Disney boxes all their "adult" stuff under the Dreamworks label IIRC.
Everybody wants to be "family friendly", which means no sexy stuff. Violence? Sure. Guns? Sure. Sex? Get that filth out of my product!
