So this is a bit of a circular argument. The example i can think of that best represents what you are saying is the toronto blue jays. For a long long time Rogers was saying we will spend more on the team if fans show up and spend money and fans just didnt believe it (sounds very familiar).
Rogers then suddenly decided to spend money aggressively in 2015 and add to the team in their competitive window. What ended up happening was a three year attendance spike. The three years was the same time frame as the financial push from Rogers.

The two way street argument does hold some water but if you have burned bridges like Melnyk has then he needs to make the first step imo (like Rogers)
