But then again
Maybe it's for the best though cause when they're saying too much
You know they're trying to get you touched
Generally when someone talks a lot it is because they are trying to cover something up or draw attention away from it (“the loudest in the room is the weakest in the room”). Jay is happier seeing his friends just keeping their head down and doing their thing than someone acting like his best friend, because that person is more likely to betray him.
This line can also be heard as “seeing too much”, meaning it would be beneficial for Jay to keep a small inner circle. If there are too many people involved in his operation that see what’s going on, there is a higher likelihood that someone could turn him in to the feds or a rival gang.
Could be an allusion to Tessio attempting to turn Michael Corleone into the rival families to be killed; Michael was able to identify him as a traitor because he was the one who approached Michael about arranging a “peace summit”, while everyone else was just doing their job.
