"Uber makes an app that lets you hail a cab, or lets you drive people around without buying a medallion." If you used Taxi's for primary transport and now use Uber, it changed your world for the better. "How about gun violence, domestic violence, cancer, diabetes, rape, systemic racism, drug overdose?" Those were not part of Uber's goal, it doesn't mean they didn't make the world just a bit better. I could say the same thing about Google or Apple. They have also changed the world but haven't addressed those issues. The difference is there wasn't regulation preventing a Google or an Apple from growing. Uber was challenging a broken system of laws protecting an industry.
