Corporate campaigns are sometimes criticized for all of the following reasons except:

A) They use the media and others to benefit the union but may hurt consumers and other stakeholders
B) They are ineffective in helping labor achieve its goals in a dispute
C) They have not stopped the decline in unionization
D) They may violate federal racketeering laws

Corporate campaigns are often criticized for using aggressive tactics and potentially hurting the reputation of the targeted company. They may also create negative consequences for stakeholders such as consumers and employees of the targeted company. However, they are generally seen as effective in helping labor achieve its goals in a dispute, which is why they continue to be used by unions. The decline in unionization is a complex issue that cannot be solely attributed to corporate campaigns. As for violating federal racketeering laws, this may apply in rare cases where the campaign involves criminal behavior, but it is not a common criticism of corporate campaigns overall.
