Yes, to "cry foul" is a commonly used expression when you want to say that someone is strongly protesting an injustice. In this case, it's used to express that publishers and the government protested strongly. Ex: He cried foul when the referee gave the point to the other team. Ex: When the president made a decision without discussion, the opposition cried foul.
