Apple does what they do, and none of us here know why. A person could guess that, given their size, it was seen as the touches and phones serving more time as a camera due to their size while that same size issue would proclude iPads from serving as cameras.
Can't say that reality plays out that way. I've been in national parks and disneyland and saw plenty of iPads being used as cameras. (Including one brave soul standing in the middle of a stream taking a photo or video with their iPad)
Using that feedback link is the best way to contact Apple. They don't play here. The most Apple officially does here is police for posts that break the rules and banning the occasional spammer. If you want your comments logged, send in feedback. Those are read and logged.
