I have received emails that make the same point, that the censorship is all about “business”. In other words, the haredi world today does not want to see Rashbam’s peshat understanding of when the day begins, so the censorship is necessary in order for ArtScroll’s mikraot gedolot Chumash to sell. Based on what I have been told by people supposedly in the know, I am inclined to believe this. This is also an appealing explanation as it is much easier to accept than that anyone at ArtScroll really believes in the justification for its censorship that was sent out and which I discussed in the earlier post.
