I understand the vulnerability of the slide up thing, but I guess what I didn't explain properly is why doesn't it open by swinging inside instead of upwards? I

  Adding a hinge there would be extra weight, but probably more importantly, the plug door is convertible to an emergency exit, so you want the hardware to be similar to the emergency exit door. For those, the door comes completely off and you throw it out of the plane when you use it. If the door hinged inward, it would take up a lot of space in the cabin during an evacuation and slow down people trying to get out. Ultimately it's extremely difficult to make a plane where you can just not install a bunch of bolts and everything still keeps working fine. You have to have a high quality manufacturing operation to make a reliable plane.

  Emergency exit doors should open outward, fall outward, etc, otherwise people rushing to get out could pile up and get stuck. True in buildings as well as vehicles. Some Airbus models have a similar upward hinge on at least some exits, I think on many the door fully detaches and you're supposed to chuck it out of the way.
