Actually, this sort of "no comment" clause in a settlement agreement is fairly common, especially when the case involves a business that deals with the public. The only unusual thing here is that these are tipsters rather than plaintiffs.
But the reasoning behind the agreement is still good. It is a fair exchange for a substantial amount of money. If they feel they can do better selling their story to the news shows, they can forgo the bird in the hand and say whatever they want.

Agreed. Money is the root of all evil. What happen to being a good citizen. That was a quick $50,000 for the guy, probably more than he made in one year. That 15 minute of fames and greed seems to go to everybody's head. They go on endless talk shows re-telling the story.
Had they reported incident to police or Wendy's company maybe company would not have suffered as much and he could have gone on every talk show.
