Apple first disapproved of adult content. Then they added rather draconian ratings for apps and of course, parental controls. Then borderline-adult content started being really popular on the store. If Apple really really really didn't want this content on the app store, they shouldn't've approved it in the first place. Can we really expect any other situation? And why couldn't Apple go one step further with ratings/controls and provide an adults-only app store area? My biggest concern (other than the lack of adult content available to me) is that Apple can first approve and be okay with selling such content, and then turn around and remove them all from the app store because other people supposedly complained too much about a specific group of apps. It was bad enough dealing with their arbitrarily defined and enforced restrictions and approval guidelines. Okay, they're the gatekeepers, and they can do whatever they want, but that makes it a lot harder for me to work as I really don't know what Apple's whims will be like when it comes to an app idea I'm considering.
