You still haven't really answered this question. Why solicit a company, have them come in and pitch, then abandon the effort and roll something out very similar later? I just think it is shitty to have them come in at all if they can reverse engineer on their own anyway.
The article also seems to mention two specific "baby brands" and names their representative at each that were spoken to. How are these anonymous sources and hearsay? In one instance, they basically admitted to knocking off labeling by agreeing to make changes to their labels to avoid confusion with the smaller brand. Though that was the anonymous source you speak of, which per your guidelines simply can't be believed.
While I wish it were less, I am glad I have only stepped into their stores perhaps five times in my life. I probably won't go back. We can certainly agree to disagree.
