This shouldn't be a big shock, a lot of experts predicted it. There wasn't any real evbidence so in A COURT OF LAW no punishment can be meted out. That's why Brady destroyed his phone. It was the only link. But you can't prove there was anything on it. So a judge has to follow the law, whereas Goodell doesn't, he can mete out justice if he believes there was wrongdoing.
As soon as this was heading to court you knew this would happen. A judge can't punish someone for what the judge thinks that person did, or what he/she suspects that he did. There has to be EVIDENCE.
Honestly how can anyone be surprised by this? It's (thankfully) how the legal system works.
Now I wonder what the Patriots are going to say about the million bucks and lost draft picks.
