Let's not mince words - Uber is not a tech company, what is their unique and newly developed technology? They are exploiting a loophole and operating unlicensed minicabs, profiting from the arbitrage of lower costs of not having to comply with regulation. Why is anyone surprised that they have a generally fuzzy idea about "rules"? It is on the regulators to shut them down.
Let's not go overboard. Uber's real time tracking, checkin, and reservation of cars, in conjunction with dynamic surge pricing to guarantee there will always be a vehicle, is pretty damn innovative - when it works. I use Uber a lot, and in the bay area, it's world class in terms of providing time estimates of arrival. In Dubai - not so much.
So - yes, lots of missteps by Uber, particularly on the ethics front, but don't discount how they revolutionized the real time tracking/reservation of cars.
