Not naming any names:
This goes back to a designer that had this warning on the selvages of her fabric sold my Moda. Some of the fabric was used in a quilt that was ultimately used on the cover of a quilt pattern book. To make matters worse, it was Moda who gave the book author the fabric to use in the first place. The designer "took legal action" because she wasn't specifically listed as the designer of the fabric in the cover quilt and she also demanded that all the books be destroyed.
I won't buy any of her fabric: if you want the name of the designer and are a clever googler, you can find out for yourself and read the original story.
