This is ridiculous. I don't see it coming into massive effect, in any case - most authors I know and follow, myself included, would rather their stuff be stolen than be altered in this sort of way.
I could perhaps see it being used in textbooks and non-fiction works, but even then, I don't think it's likely. Writing is an art, and every word choice is intentional. Screwing with wording and punctuation screws with the work and the author's intention itself.
