Nothing to worry about:
#1 the LEMs look different because they were photographed on different missions.
#2 quote"NO explanation was ever given by NASA for this silly ladder design requiring astronauts to make a blind, backward jump down to the surface." NO explanation necessary because the astronaut didn't have to make a blind, backward jump as he jumped down onto the landing pad which was well known.
#3 he's mistaking the ladderstringer with something else. I don't know what it is but Neil's hand clearly is closed around a thin and frail stringer. Moreover, even a suspicious ladder doesn't explain how all the other phenomena apparent in a low gravity evvironment (falcon feather experiment, dust parabolas, golf ball flight, rover "dancing" etc) have been faked.
They haven't that's it
