If you are sending the disks back, don't be rude about it. Sure, Lucas is a dick, but we don't have to be one either. For those who want to, when you buy the disks, take the SE and send them back with an appropriate note that simply states that
a) The 1977, 1980, and 1983 versions were the only ones you truely wanted
b) You have no use for the revised versions
and/or
c) You already have this version since you bought the 2004 box set and have no need for yet another copy of the same movie
If we are CIVIL about this, our point will be made subtly without a lot of "wah wah wah, the fans are never happy" talk people are spreding. We are going to buy his movies. It is up to us to let him know which version we prefer since both are in the package. Because, how else is he truely going to know?
