No, while the first part of your post is definitely true, the latter part is not. Actually, the fact that the people booing are paying customers makes management more concerned (not less concerned) about their sentiments than they would be about what gets posted on a site like this one or what Jay Marriotti writes in a column. The booing is an embarassment to management, particularly with a team like the Cubs, who are very visible because of their television deals. One can certainly make the argument that Latroy, Sammy, Hundley, Corey, etc would have been shown the door without boos from the fans, but the fans probably do make an impact on roster decisions. Like it or not, a lot of people go to Wrigley for the nostalgia of the park and (if the people around you aren't TOO drunk) the pleasant atmosphere. If fans create a negative atmosphere, part of the appeal of the Wrigley experience diminishes, and management has to do what most other teams have to do: field a winning team to sell tickets. It's not unrealistic to argue that such a thing could happen. In 1997, when I first moved to Chicago, average attendance was just barely over 27,000. It wasn't impossible to get Cubs/Cardinals seats at the ticket window on the day of the game.
