Looking at their app they do a lot more than just give rides nowadays. UberEats delivers from restaurants, but also apparently groceries now? They have a short-distance package delivery option. Rental cars. And some kind of tool to book a plane and hotel for travel?

I don't know if it's the right business call, but Uber is like 10 different companies now.

Because taxi business isn't actually that great business. You have to employ lot of relatively expensive drivers and they have to pay for costs of complex machine... And the users want to get it as cheap as possible and complain somewhat if prices ever go up.
