Well he was far enough not to trip the transponder

Tripping the transponder is for the amount of movement, not the absolute position. Drivers would park further back and jump start in a way they'd be still behind the white grid marker is it were any other way.

no matter what the camera suggests.

The camera suggested nothing. It showed clearly that the wheel was too far ahead before the red lights were off and section C does not mention the transponder. The stewards made an error by not properly reviewing the evidence, just as they originally noted the wrong incident and later during the race filed a correction. That's it. Mistakes happen, it's too late to apply a penalty. Doesn't mean that we cannot recognize that.
