(I am a sales and marketing professional, and have read, thought and discussed this topic at length for past 5 years).
I think "dangers of formula" is incorrect. I prefer to say "the risks of not breastfeeding" for several reasons.
1. "dangers of formula" could lead moms to think formula itself is harmful and use other substitutes. In a common person's terms, "formula" is a commercially produced mass marketed product name-brand product. So if we only say "dangers of formula", they may think home-made substitutes are okay then. I personally know people who recently (in the past 10 years) raise their babies on milk, water and corn syrup. I have heard of poor families here feeding coffee-mate, or kool-aid in bottles.
2. for the most part, I believe that the health risks that usually listed, are due to the nutrients and antibodies that are not available in formula. Some of these, such as live antibodies, would never be available.
3. In a few instances, - they ARE severe and immediate risks directly associated with formula itself - when it is contaminated (powdered formula CANNOT be made sterile, and it is NOT recommended for use by NICU or health-compromised babies - there have been documented cases of babies who have died directly due to use of powdered contaminated formula) Formula can also metal fragments or other contaminants of the manufacturing process, just like any other product. Recently (in the past year) formulas in Israel and China have missed key nutrients, and babies have died within weeks/months of using that brand of formula. So I think we CAN easily and correctlys say these are dangers of formula. A mom wouldn't want her baby to have ONE DROP of any of these formulas.
4. Life is about "risk" and more correctly "relative risk". That's why we should talk about risk. This language becomes really important when we are talking about subjects like contamination in breastmilk, or HIV moms and breastfeeding, when there potenially IS risk to breastfeeding. But the relative risk of NOT breastfeeding may be greater than the risk of breastfeeding. Relative risk is also usefull language when discussing co-sleeping, and breastfeeding and dental health.
5. Beyond one year or so, formula itself is not really a factor in this arguement. In Canada here where we have good initiation and one year maternity leaves, at some point our issue may be to encourage moms to breastfeed for 2 years or longer, as per WHO recommendations. So then we have to talk about "risk of not breastfeeding", that the child's immune system is not mature until age 5, and the child needs the support of the mother's immune system, through her breastmilk, to fight disease and illness (so the child can be healthy and use their energy to grow and learn, rather than fight colds and ear infections) and to allow their immune and nervous system to develop in the correct nutritional environment.
6. I'm very sorry that the moms here that need to use formula to supplement feel that they may be somehow harming thier children with formula. We as a society should be providing milk bank milk for them. But I don't think they should be worrying about the formula they are using. They are absolutely making the best of the situation.
Kids are bugging me, and I have to go, I'll send this and might add more later.
