Companies love data. Every last of one of them from your local grocery store to Apple. Love it, want as much of it as possible. Heck, most of the major publicized features of iOS 5 put your data on Apple's servers (iMessage: your texts and MMS; Siri: pretty much every thing including searches, calendars, and email; iCloud: it is called iCloud).
Long and short of it is that if you want privacy beyond "I'm boring, so no one cares", a device that holds pretty much every important bit of info about you made by large corporations that is nearly always connected to the internet via carriers isn't really for you.
