It has become a hot topic because Murray seems to be public enemy number one when it comes to this issue. Opposing teams have said when they scout the Leafs ahead of their games, they are told to watch out for these instances. He was seen wiggling the net, something that the opposing goaltenders don't generally do or at least as often as Murray, and sometimes when a dangerous situation is about to occur, the net seems to find itself dislodged - during the aforementioned Wild game it came off 3 times. Now, with another 2 times in Philly, apparently GMs are not pleased.
We can neither confirm nor deny whether Murray is doing this with actual intent but it is something to keep an eye on. Russo responded to several tweets where fans said he was being closed-minded and accusatory, saying: "I was IN the Situation Room and I am telling you the league is watching and clipping these examples because it's an epidemic with him and others."
Other general managers are on the lookout, some angrier than others, and it is something that the NHL is going to look at and scrutinize moving forward.
