Oh, I'm in complete agreement. Just being particular about a couple of points, 1. the issue is (at a minimum) non-anamorphic vs. anamorphic transfers, not letterboxing vs. anamorphic (that's a lazy and inexact difference), and 2. the materials to do at least a anamorphic transfer much less a full digital restoration and transfer are out there.
I would expect at least you to appreciate the specificity.

One of the amazing things to me about all of this is that restoration experts are of an age that saw the original versions in the theaters and they're as annoyed by this as much as anyone because they know it could be done right.
