Here is a novel concept, a person can be displeased by certain aspects of a process and still choose to participate in the process. That same person can speak out as to how they think the process can be improved and still actually understand the process.
I voluntarily live in the United States, I may not like everything about it, but fortunately, I am free to engage in conversations as to how it can be improved. People telling me "if you don't like it, move to X country", are just being naive and fearful of change. So for someone to tell me "stop watching the Packers if you don't like the economics of the game" is right up there with me telling them to stop watching when they complain about the officiating or some other aspect of the game.
For those who think that the economics of the NFL only occur in a tiny bubble, one that only involves and effects those who directly participate in it, think harder.
