(OK, I wanted to commented that quote but some bug is avoiding to add anything other than inside the quote, so, here's this new post here:)
In the same way, people shot in 35mm film to deliver VHS. This argument is nonsense. Proper 4K downsampled to 1080p, 720p, SD, etc is miles away of anything natively shot lower, as for instance, in the same resolution to deliver. Period.
*Sigh* :-)
