Hmmm, could have swore it was directed at someone and not just a harsh criticism of a product. Note the "the nicest thing I can say" part. It's a dog whistle to other TB haters basically stating "I'd be a lot harsher if I could, but proper etiquette dictates I keep things relatively civil." It's basically a "I'm not X, but..." or "He/she was no angel" statement because it's adding a caveat to something that most can agree it either isn't the appropriate time for it or it just shouldn't be there at all because adding caveats to young people dying of cancer is repugnant. She's not being slick by going down that route and assuming others will buy it as a neutral stance.
