It's not being "republished," it's just being edited. In fact, I'm just sending in a new unedited version purchased at retail to a company that makes edits for me that I requested. That's not "publishing."
The company is profiting off of it. And they don't have the permission to do it. If you do it on your own, that falls under fair use, but you can't go and make changes to copyrighted materials and distribute or sell them. Its a property rights issue.
