We may be narrowing in on the essence of our disagreement, Charlaquin.
I feel a retcon is not just a newer version. It is an ex cathedra disavowal by the company of what came before, a pronunciation that "That thing didn't happen, and you are wrong if you continue to think it does."
It's insulting to anyone who loved the old version. Yes the old version still physically exists. No enforcement arm will come to your house to take it from you.
But it's still diminishing and mean and again, even worse, unnecessary.
