What you listed are not Apple features but what Apple (not me) considered "hacks". Apple made the Camera Connection Kit to connect cameras.
So Apple features were not removed that I know of, only added.
Do you actually own an Apple camera connection kit? There are two devices, included in it. One an SD card reader, and two an USB adapter. My Camera Connection Kit read my USB Memory Stick, just like the SD card reader would read SD Memory Cards. This was included in the manual/sheet that came with my reader. Question just how many "Cameras" do you own, that the Camera plugs into your SD card reader, and not an SD card? There was no "hack" until Apple hacked my device, and prevented this feature. That's the equilivant of buying a station wagon, and having it serviced, and returned with the rear filled with cement, because people where putting grocery bags on the rear seats, rather than using them to transport people as envisioned by the designers!
When I purchased my iPad one could load any firmware one desired on it, now the only firmware Apple signs is the current one, forcing one to upgrade, over time. My iPad was far more stable with 3.x firmware as far as Safari goes than with 5.1.1 firmware. A lost of usefulness! I'm not asking for a camera, that my iPad wasn't sold with, but by the same token, it is wrong to force me to upgrade, and in the upgrade process install a governor that limits my maximum speed, to less than highway speeds!
Just who actually
owns my iPad after I have bought it? Me, or Apple? If I want flash on my iPad, what right does Apple have to deny me, or anyone else Flash? Does Ford or GM have the right to band, homosexuals from your car, because they don't like them? Or how about, obese people, because the gas mileage might be poorer with two or more people in the car?
ITunes by design silently deletes older Apps and replaces them with newer versions, now. The newer versions sometimes don't support the older firmware, again applying pressure to upgrade.
Apple claimed that the iPad didn't need a "Weather app" and that their developers would soon have a wealth of weather apps available for the iPad, yet show me one app that puts weather info in the Notification Center. Apple claimed that the iPad would get multitasking, yet the only way I can count on getting an alarm to go off on my iPad is to leave an app running full screen. Want to "listen" to a video running in the background? There was a firmware version that supported this feature, but once again Apple choose to remove it...
