Here we go with the "Well they could have been cheating but i guess we'll never know"
As if that doesn't apply to every single team 
Get real Grape. The only things we can go by are the evidences presented to us. The fact is that the Patriots scored more points when the balls WEREN'T deflated, then when they were. So their method of getting an advantage on the competition actually backfired. Not only that, but many other teams including the Packers were caught doing the same deflating methods with the footballs and were outed.
What are the two common themes after that? 1. Patriots are the only team that continues to get mentioned 2. All of the other teams suck.
Spygate is what literally every team in every sport does. This is why coordinators cover their mouths with their clipboards and same with base coaches signaling and covering their mouths.
Never said anything about deflategate, as it has nothing to do with what I'm talking about. The treatment they got with deflategate, however, was the result of their actions in Spygate, and their arrogance and lack of cooperation during the investigation.
As for your other statement, Spygate is NOT what every team does, not even close. That's a pretty ignorant statement, considering everything that was revealed since. Other team's cameramen didn't wear disguises, they didn't have a full time employee deciphering codes, and didn't have the NFL's help covering it up:

Felger and Mass themselves have explained this.
