Oh, I know it's not air-tight. I say it's a major concession because large ISPs seem to see municipal broadband as a huge wrench in their plans, so taking away their ability to fight it would not just be some sort of 'lip service' concession that they don't really care about. As for forcing them to stop + lobby for it? You might even run into some Supreme Court issues, and they might challenge it on free speech grounds. It would be an uphill battle for something that might not even be enforceable (which is why I also said that it's not enough of a concession to make the merger a net public gain).
