Don't get this. Its not like this doesn't happen in almost every MLB city in any almost any sport when teams win.
When I was in Anaheim last week a bunch of scalpers approached me to sell me tickets for Friday night. I said "they must be going fast with Price on the bump". One guys response was: "LAA fans are too stupid to know the pitchers so it doesn't matter".
Casual fans are the vast majority of the fan base. They chase winners and so does the corporate money for entertaining clients.
I just hope some of them stick around to become better more educated, loyal baseball fans based on the excitement Jays generated for this great game. Its good for the Jays and good for baseball to have the stands packed.
