Well, I'm glad to see you speak up for the cover artists, and the basic decency behind your argument is part of why I read your books; there's a reflection of lovely values in the telling (despite the truth of separation discussed earlier). And, as you once observed with good humor "Someone on the internet is wrong! oh no!" In this case, someone with a mote of technology in hand is being a jerk. Well, w/ 7B people or so, some few of them simply are jerks. And others, while generally decent, periodically have their moments (we all do). And, slightly further afield, there's tons of evidence that (and why) modern tech often brings out worse behavior. As noted above I'm glad to hear you speak up eloquently for those who have worked with you, but I do hope you don't let the inevitable tail of the distribution ruin your mood or your morning (day, by now, back East).
It would be a loss to have everything redone in the fashion of the day; we would lose so much. I enjoy seeing work from different eras, and all (including today, which is obvious to any thinking person) are inherently dated by an attempt to be current. Finally, of course, dated covers (or art of any sort, really) eventually become cool again; I used to collect those old 2-novels-back-to-back from the alleged golden age of sf (which wasn't, really, but was nice in it's own way).

happy trails,
