That could happen - at least in Brazil. The local Association of Toy Manufacturers (Abrinq) wants to sue companies who distribute toys along with food - McDonald's included (Molleindustria, take note).
According to Abrinq's president, that would not be motivated by the fact that some of those toys are manufactured in other countries, but because this kind of gifts would make children associate toys with a half-hour fun period, menacing the industry's image.
It's great to see people taking play seriously, and I wish I knew more details of the case. But I still can't see what's wrong with half-hour fun periods. That is, I believe, the length of the recreational break between classes in most schools.
Maybe they should extend it.
