Let's see...
Why would anyone expect anyone to react to a complaint?
One citizen reports another citizen for what the 1st citizen believes to be a crime or a civil violation.
There are law enforcement entities in place to deal with just this exact situation. There are trade organizations that have the ability to set standards of practice. These groups are in existence for the sole purpose of receiving, investigating and acting upon complaints.
Why would anyone expect them to act? Am I alone here, or is there anyone else who thinks that it is obvious that you would expect a body of legal or civil authority to act upon reports of mis-conduct or crime or other violation? At the very least, to investigate?
IMHO it boils down to fair trade. There is no argument that can support piracy and its effects on the market place, whether you believe them to be minimal or cataclysmic, as fair trade.
That is what I believe to be one of the great things about citizenship, you aren't "just" anything. Your voice has "just" as much weight, as much validity as anyone else's.
