Numerous illegitimate app stores steal Apple’s thunder

There are plenty of reports of various App Stores popping up that promise to offer iPhone applications in a way other than through the actual iTunes App Store.

These App Stores—which are completely illegitimate in Apple’s eyes, I’m sure—offer to bring numerous applications that Apple won’t allow in the store, such as tethering (which is already available on the Cydia store). Should Apple care?
