The problem is that we often attach a company or a larger idea to a single person, even when it is much much bigger than that individual. People started boycotting Tesla because of Elon Musk, without considering that Tesla is actually thousands of engineers, workers, and managers. And majority of decisions are not done by Elons.
But people tend to think in terms of heroes and anti heroes. Cesar Chavez is another example of how this dynamic plays out.
