I think anybody can sell well organized ebook on commercially. But the author is not the Wimedia Foundation exactly. I think the seller eM publication's business is illegitimate. It is a trademark infringement if the foundation did not permit the use.

Hi, all!
I searched "Wikimedia Foundation" by chance and a lot of Wikibooks, possibly collections of Wikipedia articles. The author of the books is "Wikimedia Foundation." I don't think Wikimedia Foundation is selling the e-books for 2~3 dollars, and I think it is a fraud. Many buyer commented that they want their money back.
I think the Foundation needs to find out the case and alert the bookshop.
