I have no disagreement with your position. What I'm trying to articulate (and I think I might be failing at), is that there's a difference between arguing against something incredibly successful because you have a bunch of valid reasons why it's a bad idea, and not being able to understand how anyone could possibly like using the thing you dislike.
The latter position will almost certainly lead you down a path of ruin as you try to make your living with technology.
If you worked for a book publisher who couldn't even conceive that people might like ebooks, couldn't fathom why anyone would ever want to read a book on a digital screen, for any reason, you'd quit (I hope).
Not someone who thinks paper books are superior because of the way they feel, or that they don't have DRM, or that you can share them, lend them, resell them, collect them. Those are valid reasons to prefer paper books.
But if you work in the book industry, and honestly can't understand why anybody would ever want an ebook, you're not someone whose opinion about the nature of the book industry I value.
As to who these people are, Dave Winer is a technologist who played a very important roll in making RSS a thing (and he wants to make sure you remember it...for all of eternity), and Robert Scoble is a technoloblogger (he writes about a lot of services/apps from a user perspective) who never met a social networking site/iPhone app/ that let him promote that he didn't like.
