I think comments and complaints are good. But at some point they can get counterproductive.

Let's imagine somebody spends their time organizing a meeting for other like minded people to come together talk about shaving. And they have found a fine establishment where attendees can purchase say yuengling and everybody's happy. Except that at meeting number 10 the tap is switched to budlite and certain fraction of the attendees start complaining that the greatness of the gathering has diminished immensely and they are not even allowed to bring in their own yuengling but are forced to just suck it up. It's pretty easy something like this to grow out of proportion and kill something that everybody enjoyed.
