I checked out Gang Green today to see what fans of the rodents were thinking about this and I didn't see any concern that "Biggie Rat" would be inclined to punish them for tampering, in fact, among the discussions about whether bringing Revis back was a good idea, was the suggested positive that, if nothing else, it could cause the Pats to have to pay more to keep him.
So where exactly does a team get the right to influence another team's fair negotiations with one of their players currently under contract?
In addition to Woody being an idiot, posters there are celebrating at the possible damage their tampering may inflict on the Pats.
This is exactly what the anti-tampering rules are there to guard against.
Considering that the league determined that CameraGate had given the Pats no competitive advantage in any game where signals had been filmed, the Pats were severely, and disproportionately hammered, when compared the league precedent.
It can be easily argued that the Rats have already inflicted tangible damage on the Pats, and could even cause them to lose a future HOF player, as well as other players whose negotiations are hinging on the Revis negotiations being finalized.
Compare that with what CameraGate cost the Pats, and I will leave it as an exercise for the reader to conclude what a suitable penalty is.
