brm hits the nail on the head. Their infant formula practices alone are horrible enough to boycott their entire business. For anyone that isn't familiar, they convince people in developing nations to switch to free infant formula so they stop breastfeeding long enough that they stop lactating and must purchase expensive formula instead. The mothers often can't make the formula hygienically either due to poor quality water or other unsanitary conditions so it can lead to many problems.
