If defaults are so unfair how did Chrome ever become the dominant browser in the first place? Build a better browser and people will use it, just like they did

If defaults are so unfair how did Chrome ever become the dominant browser in the first place? Build a better browser and people will use it, just like they did with Chrome. Probably won't happen today, not because of Google being the default, but because browsers are a mature product and it just isn't nearly as easy to make something noticeably better.
