The responsibility of an enterprise in this situation is to make sure that its message is clear and never ambiguous. For a long time, Nestle has been manipulating its customers with fake advertisements that contradicted one another.  According to the Guardian '' 

In South Africa, Nestle used sucrose in infant milk formulas, while marketing its Brazilian and Hong Kong formulas as being free of sucrose “for baby’s good health”. In Hong Kong, it promoted its baby milk powders as healthier – because they were free from vanilla flavourings – even as it sold other vanilla-flavoured formulas elsewhere in the territory.''

Although in this case  Nestle never advocated that their product as an alternative to breastfeeding, a Company of such Caliber should know that it is quite frequent for the general public to misinterpret the message. 

Nestle could have investigated those regions without engaging in business with them. All of this could have been avoided if there wasn't a message barrier between Nestle and third world countries. Nestle could have focused on descriptive advertisements and also emphasized the fact that milk powder is more of a supplement rather than an alternative for breastfeeding. in the past Nestle participated in unethical ads.
