This post is about Costco boycotting the company who commissioned and approved the ad to represent them and their products. How would you propose costco boycotts a TV network that they have no direct ties to? You do understand costco is a retail chain that sells physical products, in physical stores. They don't operate the TV networks or manage internet personalities and their sponsors. Short of putting out broad statements claiming NBC or Fox or whoever support domestic violence (which would open them up to slander and libel lawsuits that they'd very likely lose), I don't know what else you're demanding they do. They stopped doing business with Callaway by no longer promoting or offering their products.
Again, none of this has anything to do with your right to address or protest the US government. I'm starting to think you might not have ever actually read the bill of rights.
