A real world comparisson could be if I went to stand outside a Wallmart store and surveyed 1,000 customers about a chocolate bar... If the comon opionion opinion was it was flavorless you wouldn't dismiss that as just a Wallmart customers opinion. nor would you call it a "vocal minority" because the millions of people who didn't take the survey or dont shop at Wallmart must think the chocolate bar is amazing.
Companies have spent billions on consumer research and the results of all that rresearch often says that for every person that complains there's 25 people that share the same complaint but remain silent about it.
