Behaving unethically often benefits people in the short-term, but in the long-term it usually ends up a net negative, especially if the behavior keeps up. Uber's founders apparently don't understand this, and have imparted to you their misunderstanding.

Not to mention the wave of lawsuits that is likely coming as Uber employees are emboldened.
