I expect they're trying to use a little psychology on the readers. It's like advertisements where there's an actor wearing a lab technician's white coat and expounding the superior quality of Healthy-O's cereal. On a surface level, we all know it's an actor wearing a lab technician's white coat, but the subconscious still responds to the authority figure and believes what it hears. So with this little ploy... the reader knows it's JWs talking, but still there's a place in the subconscious that gets the idea it's somebody else, a non-JW, a narrator-type figure who has done his homework and wouldn't be saying these things about JWs if they hadn't been documented in independent tests.
Nifty terminology you hear every day, that's intended to make you think they said something else:
"No other product does more." - you're supposed to hear "This product does more than all others" but that is not what they said. Actually, the products all perform exactly the same.
"A part of this nutritious breakfast" - Okay. But it's necessary to show the nutritious part in order to get to use the word. If the fruit, juice, eggs and so forth weren't there, would they be able to show you the cereal by itself and say "this is a nutritious breakfast"?
"Got bad credit? WE DON'T CARE! ALL applications are accepted." Yes, if you hand them the application, they will certainly accept it. But that doesn't mean it will be approved.
"Save more!" - than what? Before you can "save" by spending money, you had to have already been intending to buy the same product somewhere else, for more money. If you weren't already in the market for it, you can't possibly "save" by buying it.
