Ultimately, local civic engagement is often what matters most to your day-to-day life, which is good. I think effective and durable self-governance must start at the local level. But we get blasted by media related to national politics at every time and season, to the point that the thought of trying to stay dialed into local government is a non-starter for many. If all the attention we can bear to allocate to politics is monopolized by the national wedge issues of the day, who will muster the volition to save the ice cream truck music?
It could also be that the single person that did complain happens to be a close friend or even related to someone else powerful, or is just influential in the area in other ways. That tilts the weighting as well.
From a young age I learned a fascinating lesson, socially speaking, is that some non trivial percent of the population does not at all mind the proverbial “Karen” causing a ruckus for the community. However, the second you stand up and tell them you don’t agree, somehow, you are the one held responsible as the troublemaker.
It’s not the initial ruckus causer that matters, it’s the conflict causer that does. Too many don’t care about change in any way, they care about “the peace.”
