A portion of the public will be swayed by the plight of the American Pipe Layers Union or whoever is potentially going to lose a little bit of business as the ads, like others of their kind, will provide them with a partial picture of the deal and telling them why this is horrible, without providing enough context for them to come to a different conclusion.
Some portion of the public outcry when something like this becomes public will be due these special interest groups effectively buying the opinions of the public by telling them what to think in the same manner they usually do.
