This is getting just plain ridiculous.

Public Domain text can be given away, sold, traded like baseball cards, or folded up and worn like a paper hat. That's the whole point. Everybody owns it. Everybody... as in the public.

"Business practices" have zero to do with what anyone can and cannot legally do with text that is out of copyright. Period. Regardless of where they obtained the out of copyright text.

What actually is in the public domain (and which portions of certain works are out of copyright) may be in dispute--or vary from country to country, but that's a different discussion.
