I know this is a difficult concept for other fanbases to wrap their heads around, but:
1) There are many ways to create a corporation. The cutthroat, profit-driven, shareholder value over everything model typical to most well-known corporations is not the only way. The Packers are quite open and honest about exactly what their stock is. The lack of appreciating value, limited voting rights, and possibility of stock buy-backs are all clearly stated and not a scam in any way.
2) Nevertheless, the stock is quite real and legally binding (hence, not “memorabilia”) in several important respects, not least of which being that it necessitates financial disclosures that no other franchise in the NFL is subject to. This transparency is of huge value to the fans, as it offers unique insights into how money is accumulated, shared, and utilized, with both direct application to Green Bay, but also the league as a whole by extrapolation. You can bet your bottom dollar that the league would pay unholy sums of money to make the Packers organizational structure go away and never replicated anywhere else in the league so they could maintain far more secrecy in the way finances are utilized. (By maintaining the oft-repeated misconception that the stock is meaningless, you are in fact participating in the NFL’s greedy propaganda campaign—billionaires everywhere thank you).
3) Even if the above points were untrue, the stock sales would be valuable for making it less necessary for the franchise to go to the taxpayers with hat in hand. The Packers have leveraged public financing far less often than their league peers for this reason, and this fact should be championed by any advocate of responsible government.
4) Finally, by tying themselves corporately to a fan base, the organization is not at the whim of a billionaire owner or group, and thus must act in the interests of the community and long-term stability of the organization to a larger degree than any other franchise, certainly in the NFL, and possibly more than any other team in professional sports. No, it does not eliminate greed and craven decision making entirely, but it does, for instance, make it all but unthinkable to uproot the team from Green Bay, and that alone is worth the sticker price to me. Enjoy Arlington.
